Unit V will begin to explain the use of specific statistical procedures that are used to quantitatively test data. These procedures are called inferential statistics. Inferential statistics allow researchers to make inferences about a population based upon the statistical testing of sample data. This is referred to as generalizing results.
Generalizing statistical results is only possible if the sample was randomly selected from the population of interest. A random sample is representative of the population. Generalizing is not possible using qualitative research methods since the subject group(s) is not randomly selected from a larger population.
Unit V study guide topics include:
- Data Analysis: Correlation and Regression
- Inferential Statistics
- Populations, Samples, and Generalization
- Testing for Relationships vs. Differences
Course Project Note (and Important Tip)
Always remember that statistical analysis can be simplified as either looking for relationships (or associations) between variables or looking for differences between group means. This unit considers statistical testing that looks for relationships between variables. When variables are related, one of two things will occur; a) as one variable changes, the other variable changes in the same direction (e.g. positive correlation), or b) as one variable changes, the other variable changes in the opposite direction (e.g. negative correlation). The statistical procedures used in this unit to test for relationships will be correlation, simple regression, and multiple regression.
To determine which specific statistical procedure is needed to test each of the six Sun Coast research problems, refer to the tabs in the data file. The tab labels will give a hint.
Instructions
Correlation and Regression Analysis Using Sun Coast Data Set
Using the Sun Coast data set, perform correlation analysis, simple regression analysis, and multiple regression analysis, and interpret the results. These will be the only 3 tabs used.
Please follow the Unit V Scholarly Activity template to complete your assignment. (See attachment template with instructions for essay)
You will utilize Microsoft Excel ToolPak for this assignment.
Example:
The title and reference pages do not count toward the page requirement for this assignment. This assignment should be no less than two pages in length, follow 7th edition APA-style formatting and guidelines, and use references and citations as necessary. Only use the above book as a reference.
Restate the hypotheses from Unit II, See below.
Sun Coast Research Objectives
All research methods are known such as particulate matter, sound level exposure, new employee training, safety training, lead exposure, and return on investment. Therefore, all involved stakeholders should have the necessary knowledge in methods of research such as collection, documentation, sampling, evaluation as well as presentation (Bell, Bryman & Harley, 2018).
RO1: To establish the influence of PM on the mean annual sick leave.
RO2: To determine the influence of safety training expenditure on the time lost.
RO3: To determine the influence of frequency, angles, chord length, velocity and displacement on the sound decibel.
RO4: To establish the influence of training status (prior and revised) on the training scores.
RO5: To establish the lead blood content level before and after exposure.
RO6: To determine the influence of consulting project area on the return on investment.
Research Questions and Hypotheses
RQ1: Does PM have a significant influence on the mean annual sick leave days per employee?
H01: There is no statistically significant evident influence of PM on the mean annual sick leave days per employee.
HA1: There is evident influence of PM on the mean annual sick leave days per employee.
RQ2: Is there a significant influence of safety training on the number of wasted time in hours?
H02: There is no statistically significant influence of safety training on the number of wasted time in hours.
HA2: There is a substantial influence of safety training on the number of wasted time in hours.
RQ3: Is there a joint and individual significant influence of frequency, angles, chord length, velocity and displacement on the sound decibel?
H03: There is no statistically significant joint and individual influence of frequency, angles, chord length, velocity and displacement on the sound decibel
HA3: There is a joint and individual significant influence of frequency, angles, chord length, velocity and displacement on the sound decibel.
RQ4: Does the training style of health and safety measures evidently impact training scores?
H04: The training style of health and safety measures evidently impact training scores.
HA4: The training style of health and safety measures have no evident impact on training scores.
RQ5: Does exposure to lead evidently increase the lead content in workers’ blood?
H05: Exposure to lead have no significant influence on the blood lead content.
HA5: Exposure to lead have an evident impact on the blood lead content.
RQ6: Is there a significant difference on the average return on investment based on the investment area.
H06: µ1=µ2=µ3=µ4
HA6: At least one area of investment had an average return on investment significantly different from the rest.
