Find the mean of the data set: 23, 32, 38, 19, 28, 27, 18, 36, 29, 26, 32(1 point)
To find the mean of the data set, you need to add up all the numbers and then divide by the total count of numbers.
Adding up all the numbers:
23 + 32 + 38 + 19 + 28 + 27 + 18 + 36 + 29 + 26 + 32 = 288
Now, divide by the total count of numbers (11 in this case):
288 / 11 = 26.18
Therefore, the mean of the data set is 26.18.
Question
Find the median of the data set: 56, 60, 60, 40, 60, 75, 40, 25, 53, 34, 62, 76(1 point)
To find the median of a data set, you first need to arrange the numbers in either ascending or descending order.
The numbers in ascending order are: 25, 34, 40, 40, 53, 56, 60, 60, 60, 62, 75, 76
Since there are 12 numbers in the data set (an even number), the median will be the average of the two middle numbers. In this case, the two middle numbers are 53 and 56.
Average of 53 and 56:
(53 + 56) / 2 = 109 / 2 = 54.5
Therefore, the median of the data set is 54.5.
