Exit Ticket (Statistics I): demonstrate mastery of statistical notation/summation and measures of center (mean, median, mode, midrange), including interpreting shape using mean vs. median. TI-Nspire permitted where noted.

Exit Ticket: Mean, Median, Mode (TI-Nspire allowed)

Ɛhia

Compute the mean of the data set: 12, 4, 9, 5, 10.
Show your work (sum and divide) or write the TI-Nspire command/menu you used.

Ɛhia

A data set has values: 3, 7, 7, 10, 13.
Which statement is true?

The median is 7 and there is no mode.

The median is 7 and the mode is 10.

The median is 10 and the mode is 7.

The median is 7 and the mode is 7.

Ɛhia

Two data sets have the same mean of 50.
Set A: 48, 49, 50, 51, 52
Set B: 0, 0, 50, 100, 100
Which statement best describes the shape/spread comparison?

Set A is tightly clustered near the mean; Set B is much more spread out and is not symmetric.

Both sets have the same spread because they have the same mean.

Set A must be skewed right and Set B must be skewed left.

Set B is more tightly clustered because it has repeated values.
