the members of the swimming team compared how many laps they swam yesterday.
swimming laps
javier (green bar), lucia (blue bar), rosa (orange bar), kendrick (blue bar), camille (yellow bar)
laps: 0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100
what is the median of the numbers?

Explanation:

Step1: Identify the number of laps for each person

From the bar graph:

• Javier: 60 laps
• Lucia: 30 laps
• Rosa: 30 laps
• Kendrick: 20 laps
• Camille: 90 laps

Step2: Arrange the numbers in ascending order

Arrange the number of laps from smallest to largest: 20, 30, 30, 60, 90

Step3: Find the median

The median is the middle value when the data is arranged in order. For a set with 5 values (odd number of observations), the median is the 3rd value.

Looking at the ordered list: 20, 30, 30, 60, 90, the 3rd value is 30.

Answer:

30
