Hi i am new to statistics and have the following table
Class Interval Mid-value Frequency Mid-value X
(No of Letters) Frequency
1-3 2 57 114
4-6 5 46 230
7-9 8 28 224
10-12 11 6 66
13-15 14 3 42
I have three questions I need to get, I have got question 1 i think, but am not sure how to work out the rest.
Can anyone help please.
i) Which is the modal class interval? = 57
ii) In which class interval does the median lie?
iii) Calculate the mean word length.
Thanks
