This statistics picture tutorial provides A basic introduction into hypothesis testing.
What happens if the p value is greater than α?
And, if the P -value is greater than α, then the null hypothesis is not rejected. Specifically, the four steps involved in using the P -value approach to conducting any hypothesis test are: Specify the null and alternative hypotheses. Using the sample data and assuming the null hypothesis is true, calculate the value of the test statistic.
When to reject a null hypothesis in statistics?
— If the p-value is less than or equal to 0.05 (critical value), the null hypothesis is rejected. Hence, the conclusion to be drawn is that there is a difference between means of heights of the population from two countries.
What's the difference between the null hypothesis and the alternative hypothesis?
This “X is not true” is called the Null hypothesis (Ho). And “X is true” is called the Alternative Hypothesis (H1). The X is called a Test Statistic (T). A delimiting value to understand the regions in which the test statistic is accepted or rejected is called Critical Value ( or significance level)
How is the p value of the null hypothesis calculated?
Mathematically, P-value is the probability of the test statistic assuming that null hypothesis is true. So, P-value is calculated as follows, — If the p-value is less than or equal to 0.05 (critical value), the null hypothesis is rejected.
