How can I know when to use ungrouped or grouped data. The formula. Without a table is easy,. Please reply back and answer 2017 gce. The frequency table is different from that, so am wondering how I answer it. Without using a table

[@jacobsichambaonlinemath5090]

The group data will be in class interval and ungrouped not, both formulas can work for ungrouped data.

[@SakalaDaniel-t8c]

The data seems like it's ungrouped but you used the formula for grouped data, what's the discrepancy between the two types of data?

[@jacobsichambaonlinemath5090]

It works

Sir is it ungrounded data

[@epakokangombe8154]

🎉🎉

[@marymukamba395]

So sir this formula falls on both grouped and ungrouped data

[@jacobsichambaonlinemath5090]

It works though you just need to replace the f in the formula with n

[@chibalechibale2523]

Ok m watching

[@bookrice-ie6zn]

So we should ignore over 60

Will the formulas give the same number
