Which of the following are steps involved in hypothesis testing in experimental design?Review LaterFormulating the null and alternative hypothesesSelecting a level of significanceConducting data visualizationCalculating the test statistic and p-value
Solution
The steps involved in hypothesis testing in experimental design are:
-
Formulating the Null and Alternative Hypotheses: The null hypothesis is a statement that the effect you are looking for does not exist. The alternative hypothesis is a statement that the effect you are looking for does exist.
-
Selecting a Level of Significance: The level of significance is a threshold used to decide whether the null hypothesis should be rejected or not. It is usually set at 0.05, meaning that the results must be so extreme that they would occur by chance less than 5% of the time if the null hypothesis were true.
-
Conducting Data Visualization: This step is not always necessary in hypothesis testing, but it can be helpful. Visualizing the data can help you understand the data better and identify any patterns or anomalies.
-
Calculating the Test Statistic and P-value: The test statistic is a number calculated from the data that is used to test the null hypothesis. The p-value is the probability of getting a test statistic as extreme as the one you calculated, assuming the null hypothesis is true. If the p-value is less than the level of significance, you reject the null hypothesis.
