# Descriptive Statistics and Assumption Testing

Descriptive Statistics and Assumption Testing

Research design refers to the specific type of study that you will conduct. Research design is normally consistent with one’s philosophical worldview and the methodological approach the researcher chooses. In this case, you are using a quantitative methodology. As we have discussed in this course, quantitative research designs can be experimental and non-experimental. You will be using a non-experimental design that can include descriptive statistics, correlational or causal-comparative research methods.

Research methods refer to specific procedures selected based on the chosen design. This is where you will provide detail on how you collected and analyzed your data. For quantitative methodologies, research methods can be quite detailed and require that attention be paid to recruitment, sampling, sampling frame, sample size, surveys, pilot tests, observations, data collection, data analysis, statistical procedures, data interpretation, coding, validity, reliability, generalizability, reporting, etc.

For this assignment, you will develop the research design for the Sun Coast project, utilizing this template to complete your assignment.

Your Unit III research design submission should include the below elements.

§ Research Methodology: Describe and justify the choice of research methodology and why it was most suitable to solve the problems. Be sure to compare and contrast this choice with the design that was not selected.

§ Research Design: Explain whether the research design is exploratory, causal, or descriptive. Provide the rationale for the choice.

§ Research Methods: Review the research questions and hypotheses you developed in Unit II, and then decide on the most appropriate research methods to test your hypotheses. They might include a combination of experimentation, descriptive statistics, correlation, and casual-comparative methods. Be sure to specify which method will be used to test which research question and hypotheses, and explain why that method was most appropriate.

§ Data Collection Methods: Specify how the data were most likely collected to test the hypotheses. Data collection methods include, but are not limited to, survey, observation, and records analysis. Be sure to specify which data collection method was used to collect the data needed for each research question and hypothesis. Please note that one data collection method could capture the data for several research questions and hypotheses.

§ Sampling Design: Briefly describe the type of sampling design that was most likely used for the data that were collected. Choices include, but are not limited to, random sample, convenience sample, etc. Explain your rationale for your sampling design selection(s).

§ Data Analysis Procedures: Specify which statistical procedures will be used to test each of your hypotheses from among correlation, regression, t test, and ANOVA. Explain why each procedure was the most appropriate choice.

Descriptive Statistics Analysis

Describe the Sun Coast data using the descriptive statistics tools discussed in the unit lesson. Establish whether assumptions are met to use parametric statistical procedures. Repeat the tasks below for each tab in the Sun Coast research study data set. Utilize the Unit IV Scholarly Activity template here.

You will utilize Microsoft Excel ToolPak. The links to the ToolPak are here in the Course Project Guidance document.

Here are some of the items you will cover.

§ Produce a frequency distribution table and histogram.

§ Generate descriptive statistics table, including measures of central tendency (mean, median, and mode), kurtosis, and skewness.

§ Describe the dependent variable measurement scale as nominal, ordinal, interval, or ratio.

§ Analyze, evaluate, and discuss the above descriptive statistics in relation to assumptions required for parametric testing. Confirm whether the assumptions are met or are not met.
