 What is a is the raw data, that is not sorted into categories, classified, or otherwise grouped, usually written in number list?

(a)  

What is the first step in solving measures of position for ungrouped data ?

• Ungrouped data involves finding class intervals

• The steps are the same

• Ungrouped data requires arranging data in ascending order

• Grouped data requires calculating cumulative frequency

What is the formula for calculating percentiles for ungrouped data?

• Pk = k(n-1)/4

• Pk = k(n+1)/4

• Pk = k(n+1)/10

• Pk = k(n+1)/100
