To find the mode of the quiz scores presented in the table, let's first list all the scores clearly:
95, 90, 80, 90, 90,
85, 85, 90, 80, 85.
The mode is the value that appears most frequently in a data set.
### Step 1: Organize the Scores
Let's sort the scores in ascending order to see them more clearly:
[tex]\[ 80, 80, 85, 85, 85, 90, 90, 90, 90, 95 \][/tex]
### Step 2: Count the Frequency of Each Score
Next, we count the frequency of each unique score:
- 80 appears 2 times
- 85 appears 3 times
- 90 appears 4 times
- 95 appears 1 time
### Step 3: Determine the Most Frequent Score
From the count above, we can summarize the frequencies as follows:
- 80: 2 times
- 85: 3 times
- 90: 4 times
- 95: 1 time
The score with the highest frequency is 90, which appears 4 times.
### Conclusion
The mode of the quiz scores is 90.
