Final answer:
To analyze and compare scores, a measure of central tendency must exist in Mathematics. One common measure of central tendency is the mean or average. The mean can be used to identify the average performance or achievement.
Step-by-step explanation:
The subject of this question is Mathematics.
To analyze and compare scores, a measure of central tendency must exist. One common measure of central tendency is the mean, or average, which calculates the sum of all scores and divides it by the total number of scores. For example, if you have a set of scores: 85, 90, 95, 80, and 75, the mean would be (85 + 90 + 95 + 80 + 75) / 5 = 85. The mean allows for the comparison of scores and can be used to identify the average performance or achievement.
Sample calculation:
Let's take a sample of scores in a test:
- Score 1: 80
- Score 2: 85
- Score 3: 90
- Score 4: 75
- Score 5: 95
To calculate the mean, add up all the scores (80 + 85 + 90 + 75 + 95) and then divide the sum by the total number of scores (5):
(80 + 85 + 90 + 75 + 95) / 5 = 425 / 5 = 85
Therefore, the mean score in this example is 85.
