mark's fifth grade class received the following scores on their science test: 100,100,50,50,90,90,70,70,80,80.Wat is the mode on the grades of the science test? Whats the answer? o.O
All five of those numbers are modes.
100, 90, 80, 70, 50

To find the mode of a set of numbers, we need to identify the number or numbers that appear most frequently. In this case, the grades Mark's fifth-grade class received on their science test are: 100, 100, 50, 50, 90, 90, 70, 70, 80, 80.
To determine the mode, we need to count how many times each number appears. Once we have done that, we can identify the number or numbers with the highest frequency.
Here's how you can find the mode step by step:
1. Arrange the numbers in ascending or descending order: 50, 50, 70, 70, 80, 80, 90, 90, 100, 100.
2. Count how many times each number appears:
- 50 appears 2 times.
- 70 appears 2 times.
- 80 appears 2 times.
- 90 appears 2 times.
- 100 appears 2 times.
3. Determine the number with the highest frequency: In this case, multiple numbers appear twice (50, 70, 80, 90, 100). Therefore, the mode is not unique. The set of numbers has multiple modes.
In this case, the mode on the grades of the science test is 50, 70, 80, 90, and 100, as these numbers appear with the highest frequency.
