This 20-question circuit has it all for a beginning stats review!
Questions about mean, median, mode and range.
Questions with two-way tables and questions with frequency tables.
Questions about quartiles and inter-quartile range.
A question which asks students to compare the standard deviations of two data sets.
Even a question to determine if a data set has an outlier.
Students will be asked to sketch a box and whisker plot and a histogram.
These are all basic questions which students should cover in an algebra course or within the first unit of a statistics course. There are no questions about z-scores, normal/skew, regression, and other more advanced statistical procedures/metrics.
There is no answer key provided since the answers are embedded in the circuit. It is how the students move from one question to the next. The teacher needs to work the circuit ahead of the students to determine when/how to use it in the classroom. A calculator is definitely needed to work this circuit (if only to avoid doing tons of arithmetic), but it need not be a graphing calculator; a scientific calculator will do.
