Unit 2

  • For      this assignment, you will define the research objectives and develop the      research questions and hypotheses to set the stage for the Sun Coast      Remediation research project.

You will utilize this template to complete the Unit II assignment.

Be sure to include the following sections in your submission, and remember to use APA-formatted section headings and subheadings.

  • Introduction
  • Research       problems
  • Research       objectives: Refer to the Introduction and Statement of Problems sections       provided in the Unit II Assignment Template to make explicit statements       as to the objectives of this study. For example, “One objective of this       research study is to determine the direction (either positive or       negative) and the strength of relationships between ABC Company’s various       consumer promotions and sales revenue. This objective is intended to       determine which promotions may be more effective and strategically       important.” Research objectives should be discussed for each problem       identified.
  • Research       questions and hypotheses: Provide research questions and null and       alternative hypotheses that align with the research objectives and       problems. For example:
    • RQ1:        What is the relationship between Promotion 1 and sales revenue?
      • Ho1         (null hypothesis): There is no statistically significant correlation         between Promotion 1 (independent variable) and sales revenue (dependent         variable).
      • Ha1         (alternative hypothesis): There is a statistically significant         correlation between Promotion 1 and sales revenue.
    • RQ2:        What is the relationship between Promotion 2 and sales revenue?
      • Ho2:         There is no statistically significant correlation between Promotion 2         and sales revenue.
      • Ha1:         There is a statistically significant correlation between Promotion 2         and sales revenue.
    • RQ3:        Are there differences in return on investment (ROI) between the various        promotions?
      • Ho3:         There are no statistically significant differences in ROI between         Promotion 1 and Promotion 2.
      • Ha3:         There are statistically significant differences in ROI between         Promotion 1 and Promotion 2.

Unit 3

  • Research      Design

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.
