1. Calculate the Mean:

To find the mean, sum all the raw scores and divide by the total number of students.

Given the scores:

• Anderson .Paak: 77
• TROPA MAGICA: 91
• Chromatics: 82
• A Tribe Called Quest: 68
• Janet Jackson: 95
• Talking Heads: 88
• Selena: 90
• Chet Faker: 77
• Kendrick Lamar: 85
• Whitney Houston: 55
• Doechii: 59
• Bad Bunny: 69

Step 1: Add all the scores: $77 + 91 + 82 + 68 + 95 + 88 + 90 + 77 + 85 + 55 + 59 + 69 = 884$

Step 2: Divide the total sum by the number of students (12): $\text{Mean} = \frac{884}{12} = 73.67$

So, the mean score is 73.67.

2. Find the Median:

To find the median, first, arrange the scores in ascending order:

• 55, 59, 68, 69, 77, 77, 82, 85, 88, 90, 91, 95

The median is the middle value. Since there are 12 numbers (an even amount), the median is the average of the two middle values (6th and 7th in the sorted list).

Step 1: Identify the middle values:

• The 6th score is 77.
• The 7th score is 82.

Step 2: Find the average of these two values: $\text{Median} = \frac{77 + 82}{2} = \frac{159}{2} = 79.5$

So, the median score is 79.5.

3. Find the Mode:

The mode is the score that occurs most frequently. From the list of scores:

• 77 appears twice.
• No other score appears more than once.

Thus, the mode is 77.

Summary:

1. Mean = 73.67
2. Median = 79.5
3. Mode = 77

4. How does changing one student's score affect the mean and median?
5. What would happen to the mean if a score of 100 was added?

Tip: The median is less sensitive to extreme values compared to the mean, which is helpful in understanding data when there are outliers!
