a. The mean of a data set is the sum of the terms divided by the total number of terms. Using math notation we have:
Mean=Sum of terms/Number of terms=10.25/11=0.9318
b.
The median is the middle number in a sorted list of numbers. So, to find the median, we need to place the numbers in value order and find the middle number.
Ordering the data from least to greatest, we get:
0.38 0.39 0.65 0.68 0.75 0.91 1.05 1.13 1.34 1.48 1.49
So, the median is 0.91 .
c. Mid range=(min+max)/2=(1.49+0.38)/2=0.935
d.
The mode of a set of data is the value in the set that occurs most often.
Ordering the data from least to greatest, we get:
0.38 0.39 0.65 0.68 0.75 0.91 1.05 1.13 1.34 1.48 1.49
Since each value occurs only once, there is no mode for this data set.
