a) To create frequency tables, the categories for gender, others, and age need proper labeling and classification of responses. Check if there are any inconsistencies or missing values in the dataset.
How to compute the composite scale?
b) For the composite scale calculations, ensure that the correct formula is applied to compute the average ratings for service quality and value items. Verify that all relevant items are included and properly weighted.
c) To compute coefficient alpha, use the appropriate statistical formula to measure the internal consistency of the scales derived from the items. Ensure that the calculations account for interrelatedness among the items and reflect their reliability.
The Complete Question
A survey was conducted among 200 individuals regarding their opinions on service quality (SQ) and value (VAL) provided by a company. The collected data includes information on gender, others, and age of the respondents, along with ratings for five service quality items (SQ1, SQ2, SQ3, SQ4, SQ5) and four value items (VAL1, VAL2, VAL3, VAL4).
Part 1: Frequency Tables
a) Gender:
Male
Female
Other/Prefer not to say
b) Others:
Yes
No
c) Age:
18-25 years
26-35 years
36-45 years
46+ years
Question: Are any problems evident with the coding? If so, take any necessary corrective actions.
Part 2: Composite Scale Calculation
Compute the composite scale for the five service quality items (SQ1, SQ2, SQ3, SQ4, SQ5) and the four value items (VAL1, VAL2, VAL3, VAL4) using the following formula:
SQ Composite Scale = (SQ1 + SQ2 + SQ3 + SQ4 + SQ5) / 5
VAL Composite Scale = (VAL1 + VAL2 + VAL3 + VAL4) / 4
Question: Compute the composite scale for the service quality and value items.
Part 3: Coefficient Alpha Calculation
Compute the coefficient alpha for each resulting service quality and value scale.
Calculate the coefficient alpha for the service quality and value scales obtained in Part 2.
A) Gender frequency table is accurate; Others and Age frequency tables need corrections.
B) Age frequency table is accurate; Gender and Others frequency tables need corrections.
C) All frequency tables are accurate; Composite scales and coefficient alpha calculations need revisions.
D) Frequency tables and composite scales are accurate; Coefficient alpha calculations need revisions.
