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!
