Hi Bob

Means,

Typist Ani:
= 5/40
=0.125

and

Typist Jura:
=10/160
=0.0625

Hence,  typist Jura is more consistent in her work, is it?

Please advise. Thanks!

Hi Bobbym,

Typist Ani can type 40 words per minute with standard deviation of 5 while typist Jura can type 160 words per minute with standard deviation of 10. Which typist is more consistent in her work?

Do i need to divide the 40 words per minutes (40/60) and (160/60) to get the mean. Or is it 40 and 160 are the value of mean?

Thanks!
