Mean
What is the mean?
the average of 2+ numbers
What is the median?
The number in the middle
What is the mode?
the number that occurs the most
What is the range?
the difference between the lowest and highest values
What is IQR?
Interquartile range (IQR)
How do you find the mean?
add up all the numbers, then divide by how many numbers there are
How do you find the median?
Put the numbers in order from least to greatest and find the number in the middle
Is there any mode if there are no repetitive numbers?
no
How do you find the range?
subtract the smallest value from the largest value in the set
How do you find the IQR?
Order the data from least to greatest. Find the median. Calculate the median of both the lower and upper half of the data. The IQR is the difference between the upper and lower medians.
