If the distance between the claimed value and theĪctual obtained results is small in terms of standard errors, the data is not far from the claim and the chances are the claimed hypothesis (data) is true. Measure that tells us how far the actual data results obtained are from the claimed data (from the null hypothesis). The test statistic represents the distance between the actual sample results and the claimed value in terms of standard errors. This is where the test statistic plays an important role. You have to extract meaningful things from it. You can obtain a whole bunch of data points for a given scenario, but When you're working with data, the numbers of the data itself is not very meaningful,īecause it's not standardized. Hypothesis testing type (left tail, right tail, or two-tail), and the significance level (α).
To calculate the p-value, this calculator needs 4 pieces of data: the test statistic, the sample size, the If the p-value is greater than or equal to α, we cannot reject the claimed hypothesis. That we can reject the claimed hypothesis.
If the p-value is less than α, then this represents a statistically significant p-value. This cutoff point is also called the alpha level (α). We set the significance level, which serves as the cutoff level, for whether a The p-value is a quantitative value that allows us to determine whether a null hypothesis (or claimed hypothesis) is true.ĭetermining the p-value allows us to determine whether we should reject or not reject a
