solving linear equations:

Example: A person can pay £15 for a membership to the science museum and then can go to the museum for just £1 per visit. For a member of the science museum, what is the total cost for 6 visits?

How to work it out:

C=1x6+15

C=6+15

C=£21

Calculating averages:

Averages from a list of numbers.

1) Mode-most common number (the number that appears the most)

2) Median- put the numbers in order, find the middle number- when there are two middle number add together then divide by two.

3) Mean- add all together-divide by how many numbers there are.

4) Range- biggest number take away the smallest number.

Estimating the mean:

1) Create two columns

2) Work out midpoint

3) Times the midpoint by frequency

4) Find the total for only frequency and midpoint x frequency

5) Midpoint x Frequency divided by frequency
