  • Bivariate distributions.
  • Conditional probability.
  • Random variables, expectation, variance.
  • Univariate and bivariate transformations.

What is a non statistical question in math?

The next type of question is the non-statistical question. This is the type of question that only has one answer. This one answer also doesn’t change. You don’t need to gather several points of data to answer the question. For example, the question, ‘What is 2 plus 2?’

Which questions are statistical questions?

The purpose of this task is to help students learn to distinguish between statistical questions and questions that are not statistical. A statistical question is one that can be answered by collecting data and where there will be variability in that data. This is different from a question that anticipates a deterministic answer.

What makes a question statistical?

A statistical question is one that can be answered by collecting data and for which there will be variability in that data. Questions that are answered with a single data point are not statistical questions because there is no variability in the data used to answer the question.
