Bias may be occurring. Bias is basically thinking someone is better than another person due to one factor, without even knowing the person. In this instance, the store manager is only hiring shift supervisors who have a degree, rather than an experienced cashier without a degree. The bias here is dependent on the employee's educational history. The manager may think that even though the cashiers are great, they still may not have the qualifications that one would pick up in college.

Explanation:
Pooled data occur when there is a time series of different cross sections with each observations not necessarily from the same unit while Panel data is sample from the same units. The main difference between them is the "units". The units can be countries, households, schools or other things we are collating data on.
In pooled cross section, random samples from different time periods and from different units are taken e.g. we can take data on number of females and males in schools A, B and C in 2020 and schools X, Y and Z in 2023.
In pure panel data, we are using the same units e.g we can take data on genders in schools A, B and C in 2020 and collect data from the same schools in 2023. Therefore the main difference is just the units we observe.
