what is the median of this data set
28, 49, 23, 7, 12, 19, 9
The median of this data set is 19.
To find the median, you first need to put the data in order from least to greatest:
7, 9, 12, 19, 23, 28, 49
Then, you find the middle number. Since there are an odd number of values, there is only one middle number, which is 19. Therefore, 19 is the median.
mean of this data set
12, 38, 13, 44, 18
To find the mean of a data set, you add up all the values and divide by the total number of values.
12 + 38 + 13 + 44 + 18 = 125
There are 5 values, so you divide 125 by 5:
125/5 = 25
Therefore, the mean of this data set is 25.
median of the data set
12, 38, 13, 44, 18
To find the median of a set of data, you need to first put the values in order from smallest to largest:
12, 13, 18, 38, 44
Since there are an odd number of values, the median is the middle value. In this case, the middle value is 18, so the median of this data set is 18.
mean of this data set to the nearest 10th
60, 65, 70, 75, 80, 85, 90, 95
To find the mean of this data set, you need to add up all the values and divide by the total number of values:
60 + 65 + 70 + 75 + 80 + 85 + 90 + 95 = 600
There are 8 values, so divide the sum by 8 to find the mean:
600/8 = 75
The mean of the data set is 75.0, to the nearest tenth.
