The HR department of an organization collects data on employees¿ age, salary, level of education, gender, and ethnicity. Which data do you think is more likely to follow normal distribution? Explain why.

  • math -

    Gender and ethnicity rare only nominal scales, so they are eliminated.

    Others might depend on the type of organization you are discussing.

    Salaries are likely to be positively skewed (pulled out to the right, e.g., higher salaries given to a few positions in management). The same with education.

    Age seems to be a possibility, but a minimum age limit is also likely to lead to a positive skew.
