What is a statistical question answer?

A statistical question is a question that can be answered by collecting data that vary. For example, “How old am I?” is not a statistical question, but “How old are the students in my school?” is a statistical question.

How do you solve a statistical question?

The solution involves four steps.

  1. Make sure the sample size is big enough to model differences with a normal population.
  2. Find the mean of the difference in sample proportions: E(p1 – p2) = P1 – P2 = 0.52 – 0.47 = 0.05.
  3. Find the standard deviation of the difference.
  4. Find the probability.

What are basics of statistics?

Statistics is a study of data: describing properties of data (descriptive statistics) and drawing conclusions about a population based on information in a sample (inferential statistics). Information in a sample is used to make inferences about the population from which the sample was drawn.

What are the main topics in statistics?

    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. For example, “How many minutes do 6th grade students typically spend on homework each week?” is a statistical question.

    What are some statistical questions?

    A statistical question is a question that can be answered by collecting data that vary. For example, “How old am I?” is not a statistical question, but “How old are the students in my school?” is a statistical question.

    Which question is statistical question?

    A statistical question is a question that can be answered by collecting data that vary . For example, “How old am I?” is not a statistical question, but “How old are the students in my school?” is a statistical question. This is because to answer the second question, you would need to determine the ages of all students in your school
