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.

[@albertinahhamweete4261]

Is it a mast to round off the mean for it to get a correct answer when solving s.d?

[@jacobsichambaonlinemath5090]

No

[@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
