Project #36993 - 2 SPSS Questions

Question 1.

The management of a large insurance company were interested in identifying factors which

might have an impact on workplace efficiency. In a hypothetical study, the following information

was collected from a random sample of the company’s employees:

Efficiency Level of efficiency at work. 

Morale Workplace morale

Stress Work related stress

Transport Mode of transport to work

ExerPartic Participation in workplace exercise program 

Experience Number of years’ experience in current position 

Health General health

The data is recorded in Wbk2_Q1.sav and more information about each variable is given in the 

labels in this data file. Assume that if a variable has no value labels, it is measured on a metric

scale.

It was suggested that people with more work experience, those who walk or cycle to work and

those who feel less stressed tend to be more efficient. There is also evidence to suggest that

people with high morale, and those who are in better health tend to be more efficient.

Recently there has been speculation on the value of work place exercise programs.

Researchers have suggested that providing an environment conducive to exercising at work

would improve work efficiency.

Various links between these predictors have been proposed:

ï‚· Employees who take part in the work place exercise program, and those who

walk or cycle to work are expected to have higher morale, to be less stressed and

to be in better health.

ï‚· Employees who are more experienced tend to be less stressed and to have higher

morale.

ï‚· Employees who are in better health are expected to be less stressed2

STA20007 Multivariate statistics

a. Look at the variables in the Wbk2_Q1.sav data file and decide how each variable has been 

measured (categorical or metric). Note that the level of measurement for all variables has

been set as ‘nominal’, so you will need to look at the information given and redefine the

‘measure’ to ‘scale’ for some variables. DO NOT recode any variables. Fill in the level of

measurement in the table provided in the Workbook 2 Answer document.

b. Suggest a specific two stage hierarchical hypothesis that is consistent with the theory

described above, and which can be tested using a hierarchical regression analysis. The

dependent variable here is workplace efficiency, and you are expected to include four

appropriate predictors. NOTE: It does not matter whether the data supports your

hypothesis or not.

c. In the hypothesis from part a, which variables are acting as potential mediating variables?

d. In order to test the hypothesis suggested in part b, which predictors should be entered at

stage 1 of the regression? Which predictors should be entered at stage 2?

Question 2.

It has been suggested that the factors which predict job performance will be different across

different types of professions. In one large accounting organisation researchers collected the

following information from a random sample of employees:

Performance Job performance. Measured on a metric scale taking values from 0 to

100, with higher values representing a better performance.

Client Ability to form good client relationships. Measured on a metric scale taking

values from 0 to 20, with higher scores representing a greater ability to form

good client relationships.

Colleague Ability to work co-operatively with colleagues. Measured on a metric scale

taking values from 0 to 20, with higher scores representing a greater ability

to work co-operatively with colleagues.

Dominance Participants were classified as either dominant or non-dominant, depending

on the extent to which they tended to dominate other people.

Sociab Sociability measures the extent to which participants enjoyed social

interactions. Measured on a metric scale taking values from 0 to 20, with

higher scores representing greater sociability.

Hypothetical data for these variables can be found in the Wbk2_Q2.sav data file.

a. It was hypothesised that dominance and sociability affect job performance indirectly through

their effects on ability to form good client relationships and ability to work co-operatively with

colleagues. Using SPSS, run a regression analysis to test this hypothesis. Save your output

file and upload it.

b. Write a concise report on the regression analysis. also include all relevant sections of the SPSS output as an appendix at the end of

this document.
