Hypothesis testing for Normal Distribution – Critical values method (3 examples)
Critical values method In this tutorial, we work through 3 examples of using the critical value method to determine, determine whether to accept or reject the null hypothesis.
Understanding Critical values (Hypothesis testing for Normal Distribution)
In this tutorial, we learn how about critical value, critical regions and how to use them to determine whether to accept or reject the null hypothesis.
Hypothesis testing for Normal distribution (One tailed and 2 tailed test)
Hypothesis testing for Normal distribution In this tutorial, we do more examples of hypothesis testing for one-tailed and two-tailed tests using the p values method.
Introduction to Hypothesis testing for Normal distribution
Introduction to Hypothesis testing for Normal distribution In this tutorial, we learn how to conduct a hypothesis test for normal distribution using the p values method with 6 simple steps.
Sampling distribution of the sample means (Normal distribution)
Sampling distribution of the sample means (Normal distribution) In this tutorial, we learn about the sampling distribution of sample means for normal distribution.

Probability tree diagrams
In this video, I introduce you to drawing tree diagrams as a way of simplifying calculations when combining probabilities. It is important that you see all three questions as they differ in style. I also introduce you to the notation of conditional probability. 1) A bag contains 5 red sweets and 3 blue sweets. Two […]
Possibility space diagrams
In this video, you are shown how to draw possibility space diagrams to evaluate probabilities for equally likely outcomes.
