Assignment 1 - Correlation Project

Details: As a researcher you will be considering the relationships between variables regularly. Linear correlation is the most basic relationship that may exist between two variables. This assignment will you give the opportunity to see how statistics can start to answer the research questions you will be faced with in your field of study.

Correlation Project Directions: Consider a possible linear relationship between two variables that you would like to explore.

1. Define the relationship of interest and a data collection technique.

2. Determine the appropriate sample size and collect the data.

3. Perform the appropriate analysis to determine if there is a statistically significant linear relationship between the two variables. Describe the relationship in terms of strength and direction.

4. Construct a model of the relationship and evaluate the validity of that model.

Assignment 2 - Benchmark - Research Project

Details: Research is an integral part of all professional fields. Designing a research study can be a complicated task that can be simplified if the appropriate techniques can be identified. This assignment will give you the opportunity to design an experiment, including finding relevant prior research, determining the appropriate sample, data analysis techniques, and discuss the results you hope to see.

Working from the topic chosen earlier in the topic selection, you will be designing your own statistical study.

In a 1,250-1,500 word report discuss the design of an experiment that would expand on or relate to the research in the previously chosen article. See the attached document for detailed instructions on how to complete the project.

A minimum of four additional scholarly resources are required.

Prepare this assignment according to the guidelines found in the GCU Style Guide, located in the Student Success Center.
