Grade 6 Statistics

What we verified before publishing

Fact-check status: passed

The following claims were verified through Perplexity Sonar before the questions were finalised. The host can reference any of them during play:

• A statistical question is one that anticipates variability in the data related to the question and accounts for it in the answers, such as asking how old students in a school are rather than how old a single person is.
• The mean is a measure of center that represents the value each data point would take if the total were redistributed equally, also acting as a balance point.
• The median is a measure of center that represents the roughly middle value of a data set when ordered from least to greatest.
• The mode is a measure of center representing the value that appears most frequently in a data set.
• The range is a measure of variation calculated by subtracting the smallest value from the largest value in a data set.
• Data distributions are described by their center, spread (or range), and overall shape, which can include clusters, peaks, gaps, symmetry, skew, or outliers.
• A population is the complete set of all elements involved in a study, such as all sixth-grade students in a specific school.
• A sample is a subset of the population selected to represent the whole group in a statistical study.
• A quantitative variable is a characteristic that can be measured numerically, such as age, height, or weight.
• Discrete variables are quantitative variables expressed only with integer numbers, like the number of children or cities visited.
• Frequency tables are a common way to organize data by showing how many times each specific value appears in a set.
• Common graphical representations for Grade 6 data include frequency tables, histograms, dot plots, box plots, and circle graphs.
