Answer:
first: Definitions
mean: the average or the most common value in a collection of numbers
(So u add all numbers and then divide the answer by how much numbers there were)
median: Is middle value.
(example: 4, 5, 6) (The median will be the middle which is 5) (But if there are even amount of numbers like this: 4, 5, 6, 7) (Then you will get the two middle numbers which in this case are 5 and 6 you add them and then divide by 2.)
standard deviation: measures the spread of the data about the mean value
Step-by-step explanation:
Now lets get to problem!
we have numbers:
24, 20, 16, 18, 18, 26, 22
the mean will be: 144 (remember now you have to divide by 7 because there are 7 numbers.)
So it would be 20.57
Now the median:
(Since there are 7 numbers you just find the number in the middle and that would be ur median.)
24, 20, 16, 18, 18, 26, 22
median answer: 18
Like we said: The sample standard deviation measures the spread of a data distribution of the sample. It is usually used to estimate the population standard deviation
So the standard deviation will be: 3.6
I hope this helps :)
