[Solved] Find the mean, mode, median and range of the following data set: 5; 7; 19; 24; 10; 17; 21; 6; 22; 5; 9

A function of the National Benchmark Test (NBT) could be to _____

A. determine a potential candidate's abilities, strengths and weaknesses to follow a specific field of study.
B. advise students on what type of financial aid they can access, based on the test results.
C. assess whether potential students qualify for regular entry or extended programmes in a specific course.
D. enable tertiary institutions to place students in any other field of study that may be available at the time.

Calculation for the value of Mean

Mean = `\frac{"Total Sum of Numbers"}{"Total Quantity of Numbers"}`

Mean = `\frac{5+7+19+24+10+17+21+6+22+5+9}{11}`

`\frac{145}{11}`

Now, Calculation for the value of Mode

Mode = Number that appears most often

So, Mode = 5 (5 is Number that appears most often from the above set of data)

Now, Calculation for the value of Median

We know that, Median = The Middle value

Median = 10

Now, Calculation for the value of Range

We know that, Range = Difference between largest and smallest values

Range = 24 - 5 = 19

Thus,The mean, mode, median and range are respectively (13,18) (5) (10) and (19) of the following data set: 5; 7; 19; 24; 10; 17; 21; 6; 22; 5; 9.
