If I add an extra data value of '5' to the list:
4, 5, 6, 6, 9
Will the mean go up, go down, or stay the same?
Go down.
Original mean = 6
New mean = 5
Find the mode, median, mean, and range of:
25, 15, 20, 16
Mode: no mode
Median:18
Mean:19
Range: 25 - 15 = 10
Highest value minus lowest value.
How do you find the median (include both "types")?
(1) put all the numbers in numerical order
(2) find the number(s) in the middle
(3) if there are two numbers in the middle add them together, press = and divide by 2.
What is the mode? How many modes can you have?
The mode is the data value(s) that occur the most. You can have one mode, more than one mode or no modes.
What is another word for the mean?
Average
For mode, median, mean and range. Two are measures of centre and one is a measure of spread. Identify which is which.
Mode: centre
Median: centre
Mean: centre
Range: spread
