Find the Standard Deviation of 6,5,5,4,5,5,6,5 and 4 Finding Standard Deviation We first need to make sure the calculator is CL ea R of all previous content

Finding Standard Deviation We first need to make sure the calculator is CL ea R of all previous content Find the Standard Deviation of 6,5,5,4,5,5,6,5 and 4

We want to clear ALL Finding Standard Deviation Find the Standard Deviation of 6,5,5,4,5,5,6,5 and 4

Yes reset all Finding Standard Deviation Find the Standard Deviation of 6,5,5,4,5,5,6,5 and 4

We really do agree AC Finding Standard Deviation Find the Standard Deviation of 6,5,5,4,5,5,6,5 and 4

We want the calculator in STATS mode Finding Standard Deviation Find the Standard Deviation of 6,5,5,4,5,5,6,5 and 4

We want the calculator in STATS mode Finding Standard Deviation Find the Standard Deviation of 6,5,5,4,5,5,6,5 and 4

We only have 1 variable Finding Standard Deviation Find the Standard Deviation of 6,5,5,4,5,5,6,5 and 4

We now input our data pressing = after each term Finding Standard Deviation Find the Standard Deviation of 6,5,5,4,5,5,6,5 and 4

Finding Standard Deviation Find the Standard Deviation of 6,5,5,4,5,5,6,5 and 4

Finding Standard Deviation Find the Standard Deviation of 6,5,5,4,5,5,6,5 and 4

Finding Standard Deviation Find the Standard Deviation of 6,5,5,4,5,5,6,5 and 4

Repeat this process until the data is entered Finding Standard Deviation Find the Standard Deviation of 6,5,5,4,5,5,6,5 and 4

We have finished inputting the data. We now need to get to where we can analyse it Press AC Finding Standard Deviation Find the Standard Deviation of 6,5,5,4,5,5,6,5 and 4

We need to analyse the STATS we have input Finding Standard Deviation Find the Standard Deviation of 6,5,5,4,5,5,6,5 and 4

Finding Standard Deviation We need to analyse the STATS we have input Find the Standard Deviation of 6,5,5,4,5,5,6,5 and 4

Finding Standard Deviation We want to see the Var iance Find the Standard Deviation of 6,5,5,4,5,5,6,5 and 4

n : The number of terms : The mean of the terms We want the standard Deviation σx Finding Standard Deviation Find the Standard Deviation of 6,5,5,4,5,5,6,5 and 4

Finding Standard Deviation Find the Standard Deviation of 6,5,5,4,5,5,6,5 and 4

This is the standard deviation of the data set To see more analysis details, analyse the data again Finding Standard Deviation Find the Standard Deviation of 6,5,5,4,5,5,6,5 and 4
