Statistical investigations resources

For this practical task students construct a composite strip graph of the nutrient groups found in three different food products.

Students display data on a back-to-back stem-and-leaf graph to show the times taken to complete two walks. The longer of the two walks is then identified.

Students complete a bar graph from information in a tally chart about the ages of students and interpret the data by answering questions.

Students conduct a practical, statistical investigation. They decide on a question, categories, conduct the survey, tally and graph the results on a bar graph.

Students use raw data to construct a table and then a bar graph of the number of runs scored in softball games. Students are also required to make a statement about the results.

Students construct a back-to-back stem-and-leaf graph for heights of trees. They then answer a question on range and make a statement comparing the heights of akeake and kōhūhū.

Students interpret a bar chart that shows the stopping distance of cars and are asked which car is safe and why.

Students are required to critique a survey and design another useful question to be included.

Students pose a question for an investigation about favourite sports. They then construct a table that could record the results.

Students construct and label a pie graph of favourite drinks from data in a table. They also interpret results involving proportions.

Students compare the overall distribution of two dot plots and describe their reasons.

Students answer questions about a bar graph showing favourite ice-cream flavours. No calculation needed.

Students read information and make statements about the information from two bar graphs.

Students calculate an average and a percentage from raw data and comment on these findings.

Students conduct a statistical investigation into the sentence length of different types of books by making and comparing dot plots.

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

Students complete a line graph to show the daily height of a lettuce plant, giving their graph a title and labelling both axes.

Students need to interpret data about travel time to school and common after-school activities and identify which statement is true from a list of given statements.

For this practical task students display given data in a stem-and-leaf graph to show what days of the month Room 6 children had their birthdays.

Students compare drawings of a healthy and unhealthy plant and decide which quantitative and/or qualitative data distinguishes them. They draw conclusions from the data. This is a mathematics/science resource.

This task requires students to answer questions about a time-series graph for two categories of data over an eight year period.

Students identify the appropriate type of graph for a statistical investigation about dice throws. They also justify the use of a histogram for an investigation about heights of people, indicating their understanding of discrete and continuous data.

Students choose the best type of graph for a selection of sets of data.

Students answer questions from a histogram of distance of discus throws. Calculation is required.

Students interpret a bar graph which shows the number of cats taken to a veterinarian in one week.
