John kept track of all his math and reading test scores throughout the year as shown in the table below.

Test 1:90math 80reading
Test 2:75math 90reading
Test 3:80math 70reading
Test 4:90math 75reading
Test 5:95math 90reading

What is the difference between the median of his math scores and the median score of his reading scores?
10

John made a 100 on his 6th Test in both math and reading. What will the range of his math scores be? What will be the median of his reading scores?
25range 95 median

Did the mode of his reading or math scores change after test 6?
I don't know this one and I forgot what mode means

The subject was suppose to be Math

I was helping my brother and I put his name. Sorry

2. Since there are 6 scores, the median of his reading scores is half way between 80 and 90.

The mode is the score that is most frequent.

For number 2 is it 85?

And for the mode question is the answer No?

Yes. Both your answers are correct.

To find the range of John's math scores, we first need to list all his math scores in increasing order:

90, 75, 80, 90, 95, 100

The range is then calculated by subtracting the lowest score (75) from the highest score (100):

Range = 100 - 75 = 25

So, the range of John's math scores is 25.

To find the median of John's reading scores, we need to list all his reading scores in increasing order:

70, 75, 80, 90, 90, 100

Since there are an even number of scores, the median is calculated by taking the average of the two middle scores:

Median = (80 + 90) / 2 = 85

So, the median of John's reading scores is 85.

The mode refers to the score that appears most frequently in a given set of data. To determine if the mode of John's reading or math scores changed after test 6, we need to identify the mode of both sets of scores before and after test 6.

Before test 6, the modes were:

Math: No mode since no score appeared more than once.
Reading: 90 (appeared twice)

After test 6, the modes would be:

Math: No mode since no score appeared more than once.
Reading: 90 (still appears twice)

Therefore, the mode of both the reading scores and the math scores remains the same even after test 6.
