Computational Thinking in Science and Math

The Central Limit Theorem


By the end of this lesson, you should be able to:

  • Explain how the shape of the sampling distribution of  is affected by the shape of the population distribution and the sample size (aka, The Central Limit Theorem)
  • Explain why the Central Limit Theorem is one of the fundamental theorems in statistics
  • Calculate the mean and standard deviation of the sampling distribution of a sample mean \(\bar x\) and interpret the standard deviation
  • Calculate the mean and standard deviation of the sampling distribution of a difference in sample means \(\bar x_1- \bar x_2\) and interpret the standard deviation
  • Determine if the sampling distribution of \(\bar x_1- \bar x_2\) is approximately Normal
  • If appropriate, use a Normal distribution to calculate probabilities involving \(\bar x\) and  \(\bar x_1- \bar x_2\)
