Statistical investigations resources

Students explain why one set of data is discrete and another is continuous.

Students are required to compare sales represented on line graphs of the total sales and the pattern of sales over time.

Students interpret information presented in a table, and calculate averages.

Students interpret a back-to-back bar graph about apples picked by comparing and identifying patterns.

Students decide on the best sample of students for a given survey and answer a multiple choice question. They also answer a question on sample size for best accuracy.

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

Students construct a box-and-whisker graph from data in a table about the results of two classes' geography tests.

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

Students construct and label a histogram of tulip heights from data in a table. They also answer questions about range, mode, median and mean.

Students interpret a box-and-whisker graph of maximum daily temperatures over time.

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

Students interpret a histogram showing the number of vehicles travelling at different speeds past a speed camera. Students need to calculate a percentage and the median to complete this task.

Students study a box-and-whisker graph of examination results for Maths and Science, and answer questions on comparison, median, range and proportion.

Students firstly find the mean and median length of pencils. Secondly students find the median, and lower and upper quartile for the number of cars that passed through the school gate.

Using data given in a table, students are required to construct a double line graph on the axes provided.

Students study a box-and-whisker graph of Social Studies marks for 4 classes. They answer questions interpreting the data, and comparing, range and best performance.

Students answer questions about a line graph showing scores in a cricket game. An understanding of slope is needed.

Students show their interpretation of a box-and-whisker graph by answering questions about the data.

Students identify and write down two examples each of discrete data and continuous data.

Students study a box-and-whisker graph and answer questions on median, quartile and outliers.

This task requires students to describe and compare line graphs of three different sets of data.

Students construct and label a line graph of time spent on Maths and Science homework, and answer questions interpreting the data.

Students construct a composite dot plot of shots at a basketball hoop by two classes. They identify the mode and range, and make statements about the results.

Students study a box-and-whisker graph of community fundraising, and answer questions interpreting the data.

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.
