One is A.12
Mean=average
Median=middle
Mode=same or double numbers which in this case is 14.
For your second question you first need to put your numbers in order from least to greatest and then chose the middle number which is 14. So your answer for your second question is D)14
For your first question you just needed to add all of your numbers and divide by how much numbers there are.
84รท7=12
Hope this helps:)
To find the mean of a set of data, you need to add up all the values in the set and then divide the sum by the number of values in the set.
For the set of data provided: 9, 7, 14, 11, 14, 15, 14
1) Add up all the values: 9 + 7 + 14 + 11 + 14 + 15 + 14 = 84
2) Count the number of values in the set: There are 7 values in the set.
3) Divide the sum by the number of values: 84 / 7 = 12
Therefore, the mean of the set of data is 12.
Now let's move on to finding the median of the data set. The median is the middle value when the data set is arranged in order.
For the set of data provided: 9, 7, 14, 11, 14, 15, 14
1) Arrange the data in ascending order: 7, 9, 11, 14, 14, 14, 15
2) Since there are odd number of values (7), the median will be the middle value.
3) The middle value is 14.
Therefore, the median of the data set is 14.
So the answers to the questions are:
1) The mean of the data set is option A) 12.
2) The median of the data set is option D) 14.
