Examples of Null Hypothesis Testing Decisions

Rejecting the Null Hypothesis

Arrange the following steps of null hypothesis testing in the correct logical order.

In psychology research, when applying the general logic of null hypothesis testing, what is the primary basis for deciding to reject the null hypothesis?

A clinical psychologist is investigating whether a new mindfulness-based intervention reduces symptoms of Generalized Anxiety Disorder (GAD). Match each part of their statistical reasoning process to the corresponding logical step in null hypothesis testing.

According to the general logic of null hypothesis testing, if an observed sample result is 'not extremely unlikely' to occur under the assumption that no relationship exists in the population, the researcher is logically justified in rejecting the null hypothesis.

Imagine you are developing a standardized decision-making protocol for a research lab. To correctly implement the general logic of null hypothesis testing, which set of procedural instructions should you create to guide researchers in evaluating their results?

In the formal process of null hypothesis testing, the first step of the logical sequence is to temporarily assume that the alternative hypothesis is true (i.e., that a relationship exists in the population).

A researcher conducts a study and finds a sample relationship that is 'not extremely unlikely' to occur under the assumption of a true null hypothesis. According to the formal sequence of null hypothesis testing, the researcher's only logically sound decision is to _____ the null hypothesis, as the observed evidence has failed to meet the threshold required to support an alternative explanation.

A clinical psychologist is evaluating a new therapy for depression. Match each scenario-based application of their reasoning to the corresponding logical step in null hypothesis testing.

According to the formal process of null hypothesis testing, if a researcher determines that their observed sample relationship is extremely unlikely to have occurred under the assumption of no population relationship, the logical conclusion is to _____ the null hypothesis in favor of the alternative hypothesis.

A statistics teaching assistant is creating a flowchart to evaluate students' understanding of null hypothesis logic. Place the steps of the decision-making process in the correct logical sequence from start to finish.
