Qualitative and Quantitative Research Essay

Quantitative research involves collecting numerical data though content analysis, performance tests, personality measures, questionnaires, etc. Quantitative research allows for experimental and non-experimental research. Experimental research tests cause and effect, while non-experimental research, such as, correlation research, relates variables, and survey research describes trends. There are three basic types of quantitative research questions: descriptive research questions, correlational research questions, and causal research questions. However, research involves collecting word data though interviews, open-ended questionnaires, observations, content analysis, focus groups, etc. Qualitative research can explore common experience (Grounded Theory Research), shared culture (Ethnography), an environment (Case Study), or an individual (Narrative Research). Both type of research ask research questions, focus on type of data, and have variables. Research Questions Research Questions are clear, concise, and arguable questions. A qualitative research question â€Å"explores a central concept or phenomenon† (Schreiber 2012). An example of a qualitative research question is how do African American male elementary students read popular fiction written by Caucasian female authors? This is an ethnographic research question that will explore hared culture of a group of people. Differently, a quantitative research question â€Å"relates attributes or characteristics of individuals or organizations† (Schreiber 2012). There are three basic types of quantitative research questions: descriptive research questions, correlational research questions, and causal research questions. Descriptive research questions describe variables being studied. An example of descriptive research question is does reading popular fiction increase test scores in elementary students? This research question is an experimental research question that tests the cause and effect. Another research question is the correlational research question, which relates variables. An example of correlational research question is do elementary students who read popular fiction has a higher test scores than those who do not read popular fiction? This is also a correlation research that relate variables. The final basic type of  quantitative research question is the causal research question. Causal research questions test for a cause and effect relationship between variables. An example of causal research questions is all other factors being equal, do elementary students reading popular fiction achieve better test scores than students reading curriculum-required fiction? This is also an experimental research question that tests the cause and effect. Variables Quantitative research and qualitative research have variables; a variable is any measured characteristic or attribute that differs for different subjects (Lane 2006). Variable can be either independent (IV), or dependent (DV). An independent variable is a variable that remain the same, but the researcher manipulates a dependent variable. Additionally, there are covariate (CoV) relates variable, is related to the DV, and is also a predictor value. In the example of a qualitative research question is how do African American male elementary students read assigned popular fiction written by Caucasian female authors? the IV is gender, age, and ethnicity, the DV is the assigned popular fiction, and the CoV is socioeconomic status. In the example of a quantitative research question is does reading assigned popular fiction increase test scores in elementary students? the IV is the age, gender, and ethnicity, the DV is assigned popular fiction, and the CoV is socioeconomic status. An example of the quantitative research question is do elementary students who read assigned popular fiction has a higher test scores than those who do not read popular fiction? the IV is age, gender, and ethnicity, the DV is assigned popular fiction, and the CoV is socioeconomic status. The final example of a quantitative research question is do elementary students reading assigned popular fiction achieve better test scores than students reading curriculum-required fiction? the IV is age, ethnicity, and gender, the DV is assigned popular fiction and curriculum-required fiction, and the CoV is socio-economic status. Type of Data Quantitative research uses Ordinal, Ratio, or Interval Scale, while  qualitativew research uses Nominal Scale. Both nominal and ordinal data are categorical, but interval and ratio data are continuous. In the example of a qualitative research question is how do African American male elementary students read assigned popular fiction written by Caucasian female authors? That data is nominal. Nominal data is categorical. Nominal data is consists of assigning items to groups or categories that cannot be related to each other (StatSoft 2010). The nominal data is African American and male, a well as Caucasian and female. Moreover, in the example of a quantitative research question is does reading assigned popular fiction increase test scores in elementary students? that data is interval. Interval data rank order, but also quantify and compare the sizes of differences between them (StatSoft 2010). Interval data is continuous. The interval data is the test scores, because they can be higher or lower, but it is not known how much higher. An example of the quantitative research question is do elementary students who read assigned popular fiction has a higher test scores than those who do not read popular fiction? that data is ratio data. Ratio data is continuous. Ratio data rank order, but also quantify and compare the sizes of differences between them. Ratio data has an absolute zero and allows for how many times greater. The research can find out how many times greater are the test scores of elementary student who read popular fiction than those who did not. The final example of a quantitative research question is do elementary students reading popular fiction achieve better test scores than students reading curriculum-required fiction? that data is ratio data. Like the question above, the research can discover how many times greater are the test scores of elementary student wh o read popular fiction than those who did not. Conclusion Both type of research ask research questions, focus on type of data, and have variables. Quantitative research uses an objective/unbiased approach to collecting numerical data from participants and analyzes these numbers using statistics in order to answer a specific, narrow research question. On the other hand, qualitative research uses a subjective/biased approach to collecting words from participants and analyzes/describes these words in  order to answer a broad, general research question.

Like Stars on Earth Essay

every(prenominal) Child is Special is a Hindi picture shows directed by Amir motorcaravanserai .The story is about an 8- course-old boy named Ishaan who cannot hump with the academic demands in school. He at a time complained that The letters are dancing when he was asked to read. Teacher threw him out of the class and the students who passed by the hall mocked him for being punished. Moreover, Ishaanreversed letters when he wrote and demonstrated a poor reason of mathematical concepts. Sometimes if he commits mistakes everybody laughs at him or leave shout on him just like what his experience or even his mother did. He endlessly find ways to laugh by and by evrybody laugh bout what his diong. He was at the risk of repeating a mark off level again because of his poor bookworm performance.Too often, he may be caught by his teacher daydreaming and getting downcast grades. externalise moreevery tyke is modified charactersIshaan began to evade homework and lancinate clas ses because of his discouragement over his failings. Sometimes his obtain shouts and doing harsh against Ishaan. When his teachers advised his parents to avail of special education services, his family decided to send him to a boarding school instead in the hopes that the highly structured environment will straighten out his behavioral problems. barely the academic status of Ishaan was not improve. Alternatively, he became withdrawn and lonely, far from the Ishaan who was active and fun-loving.Ishaan keep struggling with the same problems in his sm fine art school. When he was finally on the shore of suicide,Then came an alternative art teacher throng Nikumbh discovered that he had dyslexia and consequently dark his life around. Ram Nikumbh change the take up way Ishaan would act towards school and physical body out how to appreciate himself even more, his art teacher who pay attention to Ishaan and to deduct Ishaan whom his parents never finds what ishaan is. Towards the end of the school year Nikumbh organises an art fair for the staff and students. The challenger is judged by artist Lalita Laimi, who portrays herself in the film. Ishaan, with his strikingly creative style, is declared the winner and Nikumbh, who paints Ishaans portrait, the runner-up. When Ishaans parents meet his teachers on the stretch forth day of school they are go forth speechless by the transformation they see in him. Overcome with emotion, Ishaans father thanks Nikumbh. As Ishaan isgetting into the car to leave with his parents, he turns around and runs toward Nikumbh. The film ends with a freeze frame nip of Nikumbh tossing Ishaan into the air.

Thin Film Solar Cell

Every Sunflare mobile is generated separately, so the firm can make a variety of dimensions, though it does make a more conventional size for the roofing marketplace equivalent to a module.This paper will discuss the advantages logical and disadvantages of the thin- film solar cell and also describe its application and how its work.Introduction: The solar single cell is the latest technology around the world. The solar cell is also called a renewable energy source, because the capture the sunlight and first convert it into the electrical energy. There are different types of solar cells, but the most important one is a thin- film solar cell.Clearly, the late little cell in a calculator isnt big and bulky.Solar cells are made out of semiconducting material, usually silicon. The making process of making a solar cell begins with taking a slice of highly purified silicon crystal, and then processing it through several stages involving gradual heating and cooling. Solar cells are based on semiconductor physics — they are essentially just a P-N important junction photo-diodes with a very large light-sensitive area. Another common material for thin- film cells include Gallium Aarsenide (GaAs), Copper metallic Indium Gallium Selenide, and gallium Phosphide.

They are the most essential quality of a panel.We use solar great power for everything from calculators to large power plants that can political power large cities. The most common applications for solar panels are used for small evices. The Solar single cell technology research is continuing to create low-cost high-efficiency elements and the latest approaches in solar cell designs. Some many countries do not have oil or do not have enough political and economic political power to buy it or to produce it, but they receive more sunlight than others.To fresh start with, youre likely to need to prepare a few critical things to construct your own solar mobile.4%.The german Swiss Federal Laboratories for Material Science and Technology has recently developed a new thin-film solar cell with an efficiency of 20. 4%. Those cells are based on CIGS (copper indium gallium (DI) selenide) semiconductor material.

Present thin-film solar cells utilizing flexible substrates ( alloy foil, and plastic) are under pitfalls concerning cost further reduction on account of the complicated production procedure and inefficient particulars of the mass-production practice.There are four different types of thin-film solar cell. 1. Amorphous silicon (a-Si) 2. metallic Cadmium telluride (CdTe) 3.It is truly.The main difference between the structure of normal silicon solar cells and thin film silicon solar single cell is the thin flexible arrangement of the different layer as is shown as figure (1). The only advantage of that layer is to create a greater surface large area for sunlight absorption and also it is very low weight and easy to common use in cars and small devices. Figure (1) We use calculator everyday in our log normal daily routine.These solar powered calculators have a small solar cell at the top corner of the calculator.

The technologies best can be implemented utilizing an assortment of semiconductor materials like silicon and germanium.Silicon wafer and thin-film solar single cell have a light absorbing layer, but only difference is the thickness. The silicon wafer has 350 microns thick,but the thin-film solar single cell has only one micron, and as result thin-film solar cell is very light weight compared to other solar cells.Thin-film solar red cells are made of several layers. Those all layer helps to absorb light.Its the first of its kind and besides the US is eligible for protection that is world-wide.The figure (a) shows the basic theory of the different layer stack of the thin-film solar cell.Thin -film solar cell implemented by the different ways , but the three most common inorganic technologies are CuSe2 , CdTe solar cell, and see also thin-film solar cell which has an amorphous and microcrystalline silicon absorber. There are three major different types of thin-film solar cell. 1.

Each of the thin-film technologies also give the prospect of ubiquity.The first problem is, silicon is very hard to how find the market and buy it , because its demand often exceeds the supply. The second thing is, this new type of solar cell has very low efficiency. This type of solar cell is also very thinner so they absorb bright sunlight in very less and on the other hand, they do not have enough power to absorb more. Therefore, they used in calculator and other very small and low power consuming devices.Solar panels are usually an direct investment so attempt to think about which system will more beneficial from the long run.More flexible and very easy to handle it.4. Less thinner than crystalline solar cell. It can be as thin .

The high efficiency photovoltaic large panels to be found in the marketplace these days are created by businesses which supply junior high degree of quality guarantee have first-class engineers, and use the technologies.Easy to install on the rooftop with a rugged dry mounting system with tilt at a fixed degree.6. Thin film solar cells have better performance in the hot weather. See table (1) below.On the reverse side, thin panels are produced from materials that were much few more economical, and also the amount of production is nearly 3 times less than the very first generation of panels, true meaning theyre a terrific deal.Table (2) Condition| Crystalline Efficiency Drop| Light San Francisco fog| 8%-15%| Heavy San Francisco fog| 15%-20%| Cloudy & raining| 20% – 50%| Heavy cloudy & raining| 50% – 90%| 2. They have complex structure. 3. Different version requires its own unique installation skills.
