TI-84 Calculator Statistics Functions

This video tutorial demonstrates how to use the TI-84 calculator to calculate the sample and population standard deviation using the one variable stats tool. It covers entering data into the calculator, using the one var stat tool, and understanding the difference between sample and population standard deviation. Instructions for older versions of the TI-84 are also provided.

What is the primary function of the one variable stats tool on the TI-84 calculator?

• To calculate the mode of a dataset

• To find the median of a dataset

• To determine the standard deviation

• To calculate the mean of a dataset

What is the first step in entering data into the TI-84 calculator?

• Pressing 'clear' and then 'enter'

• Pressing 'stat' and then 'enter'

• Pressing '2nd' and then 'stat'

• Pressing the 'mode' button

How do you clear old data from a list on the TI-84?

• Select the list and press 'delete'

• Go to the top of the column, press 'clear', then 'enter'

• Press '2nd' and then 'clear'

• Select the list and press 'reset'

Which list should the data be entered into by default when using the one var stat tool?

• L2

• L3

• L1

• L4

What should you do if the frequency list is set to L2 but you don't have a frequency table?

• Leave it as L2

• Set it to L3

• Change it to L1

• Clear it by pressing 'clear' and 'enter'

What symbol represents the sample standard deviation on the TI-84?

• Mu

• S, X

• Rho

• Sigma X

For the sample standard deviation, what is the denominator of the fraction?

• n + 1

• n - 1

• 2n

• n

What is the default location for data entry on older versions of the TI-84?

• L2

• L3

• L1

• L4

How do you enter L1 on older versions of the TI-84?

• Press '4th' and then '1'

• Press '3rd' and then '1'

• Press '2nd' and then '1'

• Press '1'

What is the approximate sample standard deviation calculated in the tutorial?

• 4.91

• 5.91

• 6.91

• 7.91
