Statistics resources

Students read the description of a number of surveys and explain why the sample is biased.

Students conduct a practical, statistical investigation. They decide on the question to investigate, conduct the survey, complete the tally chart, and construct and label a bar graph.

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 conduct a practical, statistical investigation. They decide on a Topic and question, conduct the survey, complete the tally chart, construct a bar graph of the major ideas and make statements about the results.

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 compare the overall distribution of two graphs and describe their reasons.

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

Students identify the most likely combination of throws for a fair coin, and explain their reasons.

Students compare a data table and a line graph and identify features that are missing or incorrect in the graph.

Students are required to explain the misleading aspects of two graphs found in newspaper articles.

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

Students interpret a scatterplot and identify statements about both details and overall information.

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

Using a diagram of a spinner, students choose the chances of the arrow landing on particular numbers.

Students interpret a tally chart to answer questions about the proportion and probability of outcomes from a coin toss.

Students show understanding of probability by selecting a fraction to represent the colours of choosing an article of clothing from a drawer.

Students determine the probability of a hot air balloon landing in various locations marked on a grid map.

Students use fractions to describe the probability of an arrow landing on different bands of a target.

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 recognise equal and different likelihoods when playing a game of chance and explain their reasoning.

Students predict whether two dice games are fair and give their reasons. They then play each game (investigate) fifty times and explain their results.

Students predict the outcome of throwing five dice and confirm their predictions by conducting an experiment and calculating probabilities. After discussing how to get better estimates, they pool their results with others to get a more accurate estimate of how good their predictions were.

Students throw two dice, add the numbers together, construct a tally chart of results, and compare theoretical with observed outcome.
