Can you compute Pearson’s r in each of the following situations? Why or why not?
a Customer satisfaction ratings (‘great’ or ‘bad’) vs total visits each month
b Length of employment in months vs gender
c Length of employment vs employee satisfaction ratings (survey: 1–5)
d Employee productivity (survey: 1–5) vs performance evaluation score (1–10)
Solution
Can you compute Pearson’s r in each of the following situations? Why or why not?
a Customer satisfaction ratings (‘great’ or ‘bad’) vs total visits each month
Pearson’s r is not appropriate because satisfaction ratings is a categorical variable.
b Length of employment in months vs gender
Pearson’s r is not appropriate because gender is a categorical variable.
c Length of employment vs employee satisfaction ratings (survey: 1–5)
we can calculate Pearson’s r because both are continuous variables.
d Employee productivity (survey: 1–5) vs performance evaluation score (1–10)
we can calculate Pearson’s r because both are continuous variables.
