For the average, sum the numbers and divide by  .
Average=
.
.
.
The median is the middle data once arranged in order.
Since you have an odd number of values, take the middle (the 10th) one.
Median=
.
.
.
The mode is the value that occurs most.
Mode=
.
.
.
The midrange is the avearge of the minimum and mazimum values.
Midrange=
.
.
.
4,5,5,7,(8),9,9,9,9
The first quartile is the middle value of the first half.
First quartile=
