Students study a dot plot of the months students' were born and answer questions interpreting the data.

This practical task requires students to collect group/class data on students opinions on desk tidiness, present their data in a 2 × 2 array and make a statement based on their findings.

This practical task requires students to collect data about gender and left- or right- handedness from a group or class, present their data in a 2 × 2 array, and make a statement based on their findings.

Students complete a composite dot plot of temperatures using a weather map of the lower North Island.

Students draw a scatterplot of a table of data and describe the relationship between the two variables.

Students construct a back-to-back stem-and-leaf graph by gender, of marks students got for a statistics assignment.

Students interpret back-to-back stem-and-leaf graphs. Knowledge of the median is required.

Students study results of a survey about car colours on two pie charts and transfer the data to a composite bar graph. They also answer an interpretative question.
