okay well for part a you have to use the last column do you understand what standard deviation represents?

- anonymous

okay well just incase you don't it basically means how accurate a value is https://en.wikipedia.org/wiki/Standard_deviation

- anonymous

the higher the deviation the less accurate

- anonymous

basically which of the three schools has the lowest standard of deviation

- anonymous

- campbell_st

well for this question I think you need to be looking at measures of spread
so I'd be looking for smallest range, IQR and standard deviation as these all measure the spread of a data set.
that, for me would be the most consistent

My answer for part A is above...

- jim_thompson5910

Rule: the lower the standard deviation, the closer the scores get and clump together. The closer the scores, the more consistent the data.

- jim_thompson5910

The symbol \(\Large \sigma\) is the greek letter symbol sigma (lower case)
it represents the standard deviation

- jim_thompson5910

yes
