Hello! First, let's write the numbers of the data:
12, 15, 13, 10, 15, 10
#1) mean of the data: we will sum all the numbers and divide by the amount of them.
[tex]\frac{12+15+13+10+15+10}{6}=\frac{75}{6}=12.5[/tex]#2) median of the data: first, we have to put the numbers in crescent order:
10, 10, 12, 13, 15, 15
Then, we have to select the middle number (if we don't have 1, we will calculate the mean of the two in the middle). In this case, we have 12 and 13
[tex]\frac{12+13}{2}=\frac{25}{2}=12.5[/tex]#3) mode of the data: is the number that appears at most in the data.
In this exercise, 10 and 15 appears twice, so we have two modes and can name them bimodal.
Mode = 10 and 15
#4) range of the data: is the difference between the bigger to the smaller value. In this exercise, the biggest is 15 and the smallest is 10, so 15 - 10 = 5 is the range.
