I need to calculate the mean and standard deviation of the following data set:
I'm using a Casio fx-82AU Plus calculator
I've been doing this:
SHIFT / CLR [9] / All [3] / [=] / [AC]
MODE / STAT [2] / [AC]
SHIFT / SETUP / STAT [3] / Frequency ON [1]
SHIFT / STAT [1] / Type [1] / 1-VAR [1]
This is where I run into a problem... How do I enter the data?
I entered it like this:
... which gave me the wrong answer.
I tried entering the 220-240 with - inbetween but it gave me an error message.
Help!
Height (cm) | 150 - | 160- | 170- | 180- | 200- | 220-240 |
Frequency | 5 | 7 | 11 | 18 | 3 | 2 |
