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
