Answers
GPT 3.5
1. What is the mean of the following set of numbers: 12, 16, 20, 24, 28?
To find the mean, add all the numbers together and then divide by the total number of numbers.
12 + 16 + 20 + 24 + 28 = 100
Mean = 100 / 5 = 20
2. What is the median of the following set of numbers: 10, 15, 20, 25, 30?
To find the median, arrange the numbers in numerical order and then find the middle number.
10, 15, 20, 25, 30
Median = 20
3. What is the mode of the following set of numbers: 5, 7, 8, 7, 10, 9, 7?
The mode is the number that appears most frequently in the set.
Mode = 7
4. What is the range of the following set of numbers: 4, 6, 9, 12, 15?
To find the range, subtract the smallest number from the largest number in the set.
Largest number: 15
Smallest number: 4
Range = 15 - 4 = 11
5. Which measure of center is most affected by outliers in a data set?
The mean is most affected by outliers in a data set. Outliers can greatly skew the mean, making it an unreliable measure of center in the presence of extreme values.
To find the mean, add all the numbers together and then divide by the total number of numbers.
12 + 16 + 20 + 24 + 28 = 100
Mean = 100 / 5 = 20
