Based on the course material, define what is meant by a variable's distribution, and recall the specific distribution details of the variable 'sex' in the example sample of 100100 university students.

Question: Based on the course material, define what is meant by a variable's distribution, and recall the specific distribution details of the variable 'sex' in the example sample of 100100 university students.

Sample answer: A variable's distribution is how the scores of individuals in a sample are distributed across the levels or categories of that variable. In the course example, the distribution of the variable 'sex' in a sample of 100100 university students is such that 4444 students have a score of 'male' and 5656 students have a score of 'female'.

Key points:

  • A variable's distribution shows how scores are distributed across the values or categories of the variable.
  • The example sample size is 100100 university students.
  • The distribution for the variable 'sex' shows 4444 students have a score of 'male'.
  • The distribution for the variable 'sex' shows 5656 students have a score of 'female'.

Rubric: The response should be graded on a 3-point scale: 1 point for defining a variable's distribution as how scores are distributed across categories/values, 1 point for identifying the sample size as 100100 students, and 1 point for recalling the exact frequencies of 4444 'male' and 5656 'female'.
