Answer

Explanation:

Step1: Understand measure of central tendency

The median represents the middle - value of a data set when it is arranged in ascending or descending order. It gives a good indication of a typical value.

Step2: Analyze given data

We are given that the median number of letters a student knew was 30. The inter - quartile range gives information about the spread of the middle 50% of the data, and the fact that 29 students knew all 30 letters and all 48 students knew at least 18 letters is additional context. But the median is the key measure for a typical value here.

Answer:

30
