1. Find the mean, median, and mode for the data set.
15, 16, 21, 23, 25, 25, 25, 39
O mean = 23.6, median = 25,mode=24 O mean = 24, median = 23.6, mode = 25 O mean = 24.6, median = 24, mode = 25 O mean = 23.6, median = 24, mode = 25
O mean = 23.6, median = 25,mode=25
To find the mean, median, and mode for the given data set:
Step 1: Arrange the data set in ascending order: 15, 16, 21, 23, 25, 25, 25, 39
Step 2: Find the mean:
Mean = (Sum of all values) / (Number of values)
Mean = (15 + 16 + 21 + 23 + 25 + 25 + 25 + 39) / 8
Mean = 189 / 8
Mean ≈ 23.6
Step 3: Find the median:
Since there are 8 values in the data set, the median will be the average of the two middle values.
Median = (23 + 25) / 2
Median = 48 / 2
Median = 24
Step 4: Find the mode:
The mode is the value(s) that occur(s) most frequently in the data set.
In the given data set, the mode is 25, as it appears three times, more than any other number.
Therefore, the correct answer is:
Mean = 23.6, Median = 24, Mode = 25
