➷ To find the mean you add together the values and divide by how many values there are:
150 + 100 + 120 + 200 + 180 + 300 + 250 = 1300
1300/7 = 185.714285
Median:
Order the values and find the middle one:
100, 120, 150, 180, 200, 250, 300
As you can see, it is 180

Answer:
a) The mean is 185.714.
b) The median is 180.
Step-by-step explanation:
a) To find the mean, you add up all of the numbers and divide the sum by the amount of numbers added:
150 + 100 + 120 + 200 + 180 + 300 + 250 ÷ 7 = 185.714
(I don't know if you are rounding or need decimals, so I will include them.)
b) To find the medium, you line up all of the numbers by least to most value and find the middle number. If there is an odd amount of numbers, you just take the middle number. If there are an even amount of numbers, you take the two middle numbers and find the mean of them both.
100, 120, 150, 180, 200, 250, 300
