Question 732:
1Answer:
No answer provided yet.§ What secondary research might you do before doing the survey?
A : Find out what will be done with the information, how the perception of absenteeism is affecting the company and get an idea about who is being surveyed (the population).
§ Other than gender what other demographic information might you want?
A :Years of experience, location, department and job functions.
§ What question would you ask on the survey to get ratio level data about absenteeism by the respondent
A :Please provide the number of days you've been absent since Jan 1st of last year.
§ Describe at least three histograms/bar charts/pie charts. Describe at least one table you would use to summarize data.
A :
1. Absenteeism rate for the company displayed in a histogram
2. Absenteeism by department in a bar chart.
3. Absenteeism by years of experience also in a bar chart.
§ Describe at least one confidence interval you might compute
A :We could show the confidence interval for the mean absenteeism by employee and mean absenteeism by department.
State at least two hypotheses you might use, specifically stating the null and alternate hypotheses and the type errors that might occur
A :
Is there a difference in absenteeism based by department?
Ho: There is no difference between absenteeism by department.
Ha: There is a difference in absenteeism by department (at least 1 department is different than the others).
Is there a difference in absenteeism based on office location?
Ho: There is no difference between absenteeism by office location.
Ha: There is a difference in absenteeism by office location (at least 1 location has different absenteeism than the others).
The type of errors that might occur for both hypotheses would be in the honest reporting of absenteeism by respondent. People know that being absent is not a good thing so there is an incentive to lie, making the actual responses suspect.
