Question

The owner of a large company is conducting a survey about job satisfaction, including questions about salary, hours, stress, and other conditions. There are about 800 employees in the company, including 100 executive positions, 650 middle-management positions, and 50 custodial positions. The owner wants to include about 10% of his employees in the survey sample.

Identify a sampling method that would lead to a representative sample for the survey. Explain why it would be a good choice and give details about the process.

Answer 3

Thnks to all of guys to look at it, atleast :)

Answer 4

lets say he chose only 10% of the same class (such as 10% of all executive positions) because it is about salary, hours, and stress, chances are you will only get their opinion, and they aren't the entire company, maybe they mistreat their custodial staff, or maybe they pay off their executive board. this is why it could be biased, they should conduct a survey for more then 10% that way they cant give it out all to the same positions and such.

Answer 11

I think you need a stratified sample to get a good response

So if they survey 80 employees (10%)

then in a stratified sample you would select

you need to calculate the following for each group

1/8 x 80 from the executive staff (100/800)

13/16 x 80 from the middle management (650/800)

1/16 x 80 from the custodian (50/800)

the stratified sample shown above would give a good representation of all employee groups and hopefully eliminate bias.


Hope this helps
