Formulate the null and alternative hypotheses: The null hypothesis (H0) assumes the absence of a significant difference or impact, whilst the alternative hypothesis (H1) contends with the claim under evaluation, contrary to the null hypothesis.

Choose a significance level: The significance level (α) represents the risk of discarding the null hypothesis when it stands true. Predominant significance levels include 0.05, 0.01, and 0.001.

Select a test statistic: The test statistic, a value standardized from the sample data, plays a pivotal role in determining the chance of observing the data under the null hypothesis.

Compute the p-value: The p-value signifies the probability of landing a test statistic as extreme or more so than the observed one, given the truth of the null hypothesis.

Make a decision: The crossroads of decision-making involve comparing the p-value with the predetermined significance level. If the p-value sinks below or matches the significance level, the journey veers towards the rejection of the null hypothesis in favor of the alternative. However, if the p-value overshadows the significance level, the null hypothesis remains intact.

Type I error: A Type I error is an unfortunate event where the null hypothesis is shunned even though it is true. The likelihood of stumbling upon a Type I error equates to the selected significance level (α).

Type II error: A Type II error is a scenario where the null hypothesis slips past rejection despite its falseness. The likelihood of a Type II error is symbolized by β, and the test's power is outlined as 1 - β.

t-test: Puts the means of two groups under scrutiny.

Chi-square test: Probes into the association interlinking categorical variables.

ANOVA: Investigates the means across more than two groups.

Correlation test: Appraises the strength and trajectory of the correlation between two continuous variables.
