Answer:
Mean = 8
Median = 8
Mode = 8
Explanation:
Finding the mean:
The mean is the sum of all the data points divided by the total number of data points. Since there are 8 data points in total, we can find the sum and divide it by 8 to find the mean:
Mean = (2 + 12 + 8 + 15 + 8 + 7 + 3 + 9) / 8
Mean = (64) / 8
Mean = 8
Thus, the mean of the given data is 8.
Finding the median:
The median is the value that lies in the middle of the data. First, we must arrange the data in ascending numerical order:
2, 3, 7, 8, 8, 9, 12, 15.
Because there are 8 data points, we have two numbers in the middle, namely 8 and 8. In order to find the mean, we find the average of these two numbers:
Median = (8 + 8) / 2
Median = 16 / 2
Median = 8
Thus, the median of the given data is 8.
Finding the mode:
The mode is the most frequently occurring value in a data set. 8 occurs most frequently so the mode of the given data is 8.
