Data is collected from 20 elves about both productivity cook

Data is collected from 20 elves about both productivity (cookies made per day) and years of employment at the cookie factory. The question is whether productivity changes with years employed.

Identify whethere the case is nominal, ordinal, or continuous type. State whether is experimental or observational.

Solution

This is a CONTINUOUS type, as the average number if cookies made per day can take decimal values.

This is OBSERVATIONAL, as we don\'t manipulate the sample, we just observe what they did historically.
