To determine which class did better on average, we look at the median scores provided for each class. The median is a good measure of "average" because it represents the middle value in a set of data.
Step 1: Identify the median for Class 1.
The problem states that the median for Class 1 is
19. This means half of the students in Class 1 scored 19 or lower, and half scored 19 or higher.
Step 2: Identify the median for Class 2.
The problem states that the median for Class 2 is
25. This means half of the students in Class 2 scored 25 or lower, and half scored 25 or higher.
Step 3: Compare the two medians.
We compare the two numbers:
* Class 1 Median: 19
* Class 2 Median: 25
Since 25 is greater than 19, the typical score in Class 2 is higher than the typical score in Class 1. Therefore, Class 2 performed better on average.
Final Answer:
Class 2 did better on average
