# Types of data analysis for quantitative research

Typically, you should not make assumptions from correlational research alone. The quantitative types argue that their data is 'hard', 'rigorous', 'credible', and 'scientific'. For instance, if we had ten statements and we grouped these into five piles as shown in the figurewe could describe the piles using a 10 x 10 table of 0's and 1's.

Mean — the numerical average of scores for a particular variable Minimum and maximum values — the highest and lowest value for a particular variable Median — the numerical middle point or score that cuts the distribution in half for a particular variable Calculate by: Study population and sampling -- where did the data come from; how robust is it; note where gaps exist or what was excluded.

Once that statement is made experiments are begun to find out whether the statement is true or not. If two statements were placed in different piles, we would use a 0. If the analyst determines the data to have a strong correlation, the data can be graphed so that predictions can be made. However survey research can be applied to the other types of research listed below.

The results are based on larger sample sizes that are representative of the population. It is generally done by collecting customer data from surveys and then using hypothesis testing quantitative analysis tools to determine the likelihood of a member of the general population to have the same response or characteristic.

Ad Linear regressions are a popular quantitative analysis tool that is used to determine the relationship between two sets of related data. Note that no data set is perfect--describe any limitations in methods of gathering data.

These graphs for quantitative analysis can be found in the form of bars, lines and dots. The search for this explanation can be presented in the form of a question. Such quantitative analysis tools require the analyst to have basic mathematical skills and can be done in most spreadsheet software.

Like correlations, causation can not be inferred from regression. Need Help Locating Statistics? Researcher has a clearly defined research question to which objective answers are sought.

Note the procedures used for their selection; Data collection — describe the tools and methods used to collect information and identify the variables being measured; describe the methods used to obtain the data; and, note if the data was pre-existing [i.

This is done with statistics. The researcher who decides to use such a scale in their study has to make another set of judgments: This level of control might not normally be in place in the real world thus yielding "laboratory results" as opposed to "real world results"; and, Preset answers will not necessarily reflect how people really feel about a subject and, in some cases, might just be the closest match to the preconceived hypothesis.

For example, the test scores of two groups of students are examined and proven to be significantly different. This module describes some of the most commonly used quantitative analysis procedures.

Upper Saddle River, NJ: A descriptive study is governed by the following rules: Generally, quantitative methods are designed to provide summaries of data that support generalizations about the phenomenon under study.

List the steps involved in analyzing quantitative data. The accuracy of hypothesis testing depends largely on the size of the sample population, randomly selecting from the population, accuracy of the questions, and errors in collecting the information.

If the analyst determines the data to have a strong correlation, the data can be graphed so that predictions can be made.

The results are then expressed as exact numbers and allow you to begin to give meaning to the data. It is generally done by collecting customer data from surveys and then using hypothesis testing quantitative analysis tools to determine the likelihood of a member of the general population to have the same response or characteristic.

They can also be used for forecasting or determining the probability of a particular event happening. These are more complex analyses and are looking for significant differences between variables and the sample groups of the population. June 9, by April Klazema Quantitative research is a type of empirical investigation.

All but one of the students of color in the Boston program were dissatisfied with their experience since there were 6 students of color in the Boston program. Variable Frequencies for Student Summer Program Survey Data A percent distribution displays the proportion of participants who are represented within each category see below.

Ad Linear regressions are a popular quantitative analysis tool that is used to determine the relationship between two sets of related data. Conclusion End your study by to summarizing the topic and provide a final comment and assessment of the study.

Frequencies — a count of the number of times a particular score or value is found in the data set Percentages — used to express a set of scores or values as a percentage of the whole Mean — numerical average of the scores or values for a particular variable Median — the numerical midpoint of the scores or values that is at the center of the distribution of the scores Mode — the most common score or value for a particular variable Minimum and maximum values range — the highest and lowest values or scores for any variable It is now apparent why determining the scale of measurement is important before beginning to utilize descriptive statistics.

The most common descriptives used are: The most common type of graph for quantitative data is the histogram.Jun 09,  · Quantitative research is focused specifically on numerical information, also known as ‘data.’ Because the research requires its conductor to use mathematical analysis to investigate what is being observed, the information collected must be in kitaharayukio-arioso.com: April Klazema.

Quantitative research, is defined as a the systematic investigation of phenomena by gathering quantifiable data and performing statistical, mathematical or computational techniques. Learn more about quantitative research methods along with types and examples, characteristics and advantages.

Also learn about primary and secondary quantitative research along with techniques and types of. terminology of data analysis, and be prepared to learn about using JMP for data analysis. Introduction: A Common Language for Researchers Research in the social sciences is a diverse topic. In some areas of social research, the qualitative-quantitative distinction has led to protracted arguments with the proponents of each arguing the superiority of their kind of data over the other.

The quantitative types argue that their data is 'hard', 'rigorous', 'credible', and 'scientific'. In quantitative data analysis you are expected to turn raw numbers into meaningful data through the application of rational and critical thinking. Quantitative data analysis may include the calculation of frequencies of variables and differences between variables.
