Thanks 😅😅😅

[@chailamangala5854]

Kindly differentiate a grouped data from ungrouped data by formula

[@jacobsichambaonlinemath5090]

Both work the same when data is in the table.

[@KanyemboCastrol]

Because when we use this formula with the one which we use a table the answers become different

[@mambwechileshe5840]

Kalebwangu ba sire😢

[@MorrisMuchabila]

How are you doing this weekend sir

[@SherineNola]

Sorry sir but just from watching a certain teacher, what you are solving is different from what he did. I don't know which one to follow but this is when am learning. Has for him his using the the mean then squares it in those blankets, you are squaring the same numbers. The formula on s.d is different from yours 😢I don't know what to do

[@DumisanNgoma-kt9kw]

Same answer different methods so it's up to you to choose the method otherwise the professor is absolutely right.. Thank you 🙌

[@sailiems2673]

But what can happen if used the other formula given for ungrouped data since there are two formulas given and this number of hours is not in class intervals?

[@MathewsChiwala-wh2vc]

What if the data is not in a table what should we do

[@OloyaGerald]

Iwish am ur student

[@MusaMakwinja]

Sir the 7 suppose to be in the brackets

[@KanyemboCastrol]

But sir why are have you used the same formula with the one for grouped data?

[@MercyAlkeriah-eq3ez]

Wherd do u stay sir?

[@BrianNgimbu]

Please do also grouped data

[@TracyPhiri-x8n]
