Do you happen to have any additional questions similar to mixed exercise 3 Q8d and 9c? My group are struggling with this and the solution bank sets out the linear interpolation using fractions.
For slide 27, should the calculation not be
19.5 + (195/240)x11 instead of
20 + (195/240)x10 as the class width for the 20-30 category is 11?
Is there a set of answers for the excellent supplementary histograms exercise?
I've fixed the errors pointed out below.
The Chp3 for S1 doesn't have the supplementary sheets for the box plots... am I looking in the wrong place for them? I can only find a histogram supplementary sheet?
Slide 24 should be a sf of 2.5 not 2.4 & then there are 37.5 people.
woah very easy and helpful im in yr7!
Thank you Dr. Frost, very cool!
slide 24 - 2.4 should be 2.5.
Thanks DF - VVP
Outlier error on Slide 8 is still there.
thank u for ur resources. i know they're going to be extremely useful. appreciate all tha you are doing
Great resources, thanks!
Slid 24 there is an error in calculation when doing 60 divided by 24 to get 2.4 when the real answer is 2.5 also the use of scaling is completely wrong
Are there answers for the histogram supplementary questions?
Fixed (again!). Looks like I accidentally reuploaded an older version earlier.
Enormous thanks for great resources.
Check Outlier examples pages. Slide 8
Upper outlier boundary =ðŸ‘.ðŸ+ðŸ.ðŸ“Ã—ðŸŽ.ðŸ—=ðŸ’.ðŸ“ðŸ“
Upper quartile is 3.6 not 3.2.
Great Resources ..massive help to students & teachers alike. Thank you
a few slips in solutions for slides 8 & 9.
Proposed corrections emailed directly to Dr Frost 25/9
Brilliant work - thank you.
