Answer :
To solve the problem and find the mean, median, and midrange of the given golf scores, let's break down each step of the calculation:
1. Mean:
The mean is calculated by summing up all the scores and dividing by the number of scores.
Scores: 68, 62, 60, 64, 70, 66, 72
Sum of scores = 68 + 62 + 60 + 64 + 70 + 66 + 72 = 462
Number of scores = 7
Mean = Total sum / Number of scores = 462 / 7 = 66
2. Median:
The median is the middle number once all the scores are arranged in ascending order.
Arranged scores: 60, 62, 64, 66, 68, 70, 72
Since there are 7 scores (an odd number), the median is the 4th score in this ordered list.
Median = 66
3. Midrange:
The midrange is found by taking the average of the minimum and maximum scores.
Minimum score = 60
Maximum score = 72
Midrange = (Minimum + Maximum) / 2 = (60 + 72) / 2 = 132 / 2 = 66
Putting it all together, the mean, median, and midrange of the scores are all 66.
Therefore, the answer is:
d. Mean = 66, median = 66, midrange = 66
1. Mean:
The mean is calculated by summing up all the scores and dividing by the number of scores.
Scores: 68, 62, 60, 64, 70, 66, 72
Sum of scores = 68 + 62 + 60 + 64 + 70 + 66 + 72 = 462
Number of scores = 7
Mean = Total sum / Number of scores = 462 / 7 = 66
2. Median:
The median is the middle number once all the scores are arranged in ascending order.
Arranged scores: 60, 62, 64, 66, 68, 70, 72
Since there are 7 scores (an odd number), the median is the 4th score in this ordered list.
Median = 66
3. Midrange:
The midrange is found by taking the average of the minimum and maximum scores.
Minimum score = 60
Maximum score = 72
Midrange = (Minimum + Maximum) / 2 = (60 + 72) / 2 = 132 / 2 = 66
Putting it all together, the mean, median, and midrange of the scores are all 66.
Therefore, the answer is:
d. Mean = 66, median = 66, midrange = 66
