Excel bell curve assistance - 22/08/2014 12:16
I am trying to draw a bell curve of some data, but for the life of me can't get it to work..
Basically I have alist of employees and their salaries, and I need to plot them on a bell curve to display their distribution.
In the first group I am looking at I have just 9 employyes, but I need to plot this for other groups, so the data could grow as much as 100 people in one group.
I have the following data in place:
stddev: 2.67
mean: £9.82
Min: £6.83
Max: £14.51
No of data points: 9 (£6.83, £7.60, £7.78, £7.78, £9.07, £9.13, £12.14, £13.51, £14.51)
I have then worked out a data table, showing my distributions, but....
IT WON'T BLOODY WORK
Can anyone please assist? Thanks as ever y'all
