Answer 1

Here are ten numbers:

3 7 2 4 7 5 7 1 8 8

a)

Write down the mode. 7

b)

Work out the median.

c)

Calculate the mean. add all and divide by 10

d)

What is the range? 7

Answer 2

Mode: 7

Median: 6

Mean: 5.2

Range: 5

Explanation:

For the mode you have to find which number is present the most times

For the median you have to find the middle number if the total sum of numbers is an odd number, and find the average of the two if it is an even number ,like i did here (7+5)/2=6

For the mean you have to add every number and then devide with the total number of the numbers given:

(3+7+2+4+7+5+7+1+8+8)/10=5.2

For the range you have to find the largest number and subtract the smallest number from it (8-3)=5
