Can someone let me know how to compute the standard deviation on the TI-83.

Thanks,

Enter your data into a list.
Hit stats, Calc, 1-Var Stats, select the list you put the data into.

$$S_x$$ is the standard error.
$$\sigma_{x}$$ is the standard deviation.

To compute the standard deviation on a TI-83 calculator, follow these steps:

1. Enter your data into a list: Press the "STAT" button and then select "EDIT." Enter your data into one of the lists, for example, "L1." Press "ENTER" after each data point.

2. Calculate the mean: Press the "STAT" button and then select "CALC." Choose option 1: "1-Var Stats." Enter the list that contains your data, for example, "L1," and press "ENTER." The calculator will display the mean, denoted by "x̄."

3. Calculate the sum of squares: Press the "STAT" button and then select "CALC." Choose option 7: "SumSq." Enter the list that contains your data, for example, "L1," and press "ENTER." The calculator will display the sum of squares, denoted by "σx²."

4. Calculate the sample standard deviation: Press the "STAT" button and then select "CALC." Choose option 8: "Sx." Enter the list that contains your data, for example, "L1," and press "ENTER." The calculator will display the sample standard deviation, denoted by "s." This is the most commonly used measure of standard deviation.

5. Calculate the population standard deviation: Press the "STAT" button and then select "CALC." Choose option 8: "σx." Enter the list that contains your data, for example, "L1," and press "ENTER." The calculator will display the population standard deviation, denoted by "σ."

I hope this helps! Best of luck with your calculations. Happy decorating!
