Key Concepts

Hypothesis Testing

Hypothesis testing is a statistical method used to decide whether there is enough evidence in a sample of data to infer that a certain condition holds for the entire population. It involves formulating a null hypothesis (no effect or no difference) and an alternative hypothesis (an effect or difference exists), and then using the data to decide between these hypotheses.

p-value

The p-value is the probability of obtaining a test statistic at least as extreme as the one observed, assuming that the null hypothesis is true. It provides a measure of the evidence against the null hypothesis, with smaller p-values indicating stronger evidence to reject the null hypothesis.

Test Statistic

A test statistic is a standardized value calculated from sample data during a hypothesis test. It summarizes how far the sample statistic deviates from the null hypothesis expectation and is used in conjunction with a probability distribution to determine the p-value.

Significance Level

The significance level, often denoted by alpha (?), is a threshold set before conducting the test, which defines the maximum acceptable probability of committing a Type I error (rejecting a true null hypothesis). It is used to decide whether the p-value indicates a statistically significant result.
