Sagot :

Answer:

Median. Explanation to each part below.

Step-by-step explanation:

a) Starting with calculating the mean, which is all the values added divided by the number of values (in this case he has 6 scores total).

[tex]mean/average=\frac{81+87+93+89+61+81}{6} =\frac{492}{6} = 82[/tex]

b) To find the median, arrange all the test scores in increasing order and find the middle/median value. We have 6 scores, so we will have 2 middle scores. If we had 7 scores, we would find only 1 score in the middle which would be the median. We will have to find the average of the two scores.

[tex]61,81,81,87,89,93[/tex]

The middle values will be 81 and 87 so find the average of those 2 scores.

[tex]Median: \frac{81+87}{2} =\frac{168}{2} =84[/tex]

c) The mode is the score which occurs the most. In this case, Jack has 2 scores that are 81, which is his mode.

d) The measure that would make his performance sound good would be the median. The mode and mean are below the score of 84 that he gets for the median. He would want to flaunt this measure to show he performs well.
