Question in How-tos
This question models an experiment: the student must collect some data and enter it at the start of the question, and the expected answers to subsequent parts are marked based on that data.
The student's values of the variables width, depth and height are stored once they move on from the first part.

Question in How-tos
This question models an experiment: the student must collect some data and enter it at the start of the question, and the expected answers to subsequent parts are marked based on that data.
A downside of working this way is that you have to set up the variable replacements on each part of the question. You could avoid this by using explore mode.

Question in Skills Audits for Maths and Stats
This question is about identifying what types of charts or visual representations of data you can use for different data sets.
-
Question in Skills Audits for Maths and Stats
Decide whether each of the described sets of data is drawn from a discrete or continuous distribution.
-
Question in How-tos
This shows how to define a list of LaTeX strings, and pick a couple of them at random to display.
The "JSON data" type is used to define the available strings, so they're automatically marked as "safe" and curly braces aren't interpreted as variable substitution.
-
Question in How-tos
This question shows how to generate a random set of $(x,y)$ samples, where $y = mx + c + \mathrm{noise}$.
The JSXGraph extension is used to show a scatter plot of the data. This isn't necessary if you just want to generate the data.
-
Question in How-tos
This question shows how to use the question's JavaScript preamble to request data from an external source, and use that data in question variables.
Note that this means the question only works when the external source is available. Use this very carefully, and avoid it if you possibly can!

Question in Demos
Several questions on interrogating the
mtcars
dataset built in to R. -
Question in Odds and Ends
Used for LANTITE preparation (Australia). NA = Number & Algebra strand. Students are asked two true/false questions based on a table of data about the LANTITE test. The pair of true/false questions are randomly selected from a pool of five pairs of questions.

Several questions on interrogating the
mtcars
dataset built in to R. -
Question in MESH
The student is presented with a scenario then asked to select a sample size to investigate and the number of bins for a histogram of the data. Theoretical distributions of normal, uniform and lognormal distributions can be overlayed on the histogram. Student is asked to identify the most likely distribution and the mean of this distribution (within a +/-10% margin of error).
-
Question in Ed questions to share
Used for LANTITE preparation (Australia).SP = Statistics & Probability strand. NC = Non Calculator strand. Students are shown an infographic and asked two of five possible true/false questions.
-
Question in Ed questions to share
Used for LANTITE preparation (Australia). NA = Number & Algebra strand. SP = Statistics & Probability strand. Students read a percentage from the chart, and calculate that percentage of the number of children (randomly generated).
