A local coach wants to see if training in light rooms or dark rooms impacts athlete performance. With the single team, the coach tries training in different conditions and takes measurements. With measurements in hand, the coach is ready to analyze in Microsoft Excel. Which test should be selected from the menu? t-Test: Two-Sample Assuming Equal Variance t-Test: Paired Two Sample for Means Fourier Analysis Descriptive Statistics
What is a potential challenge of a matched samples study design? Equivalence is controlled Potential test fatigue of subjects Less people are required for the study
Which of the following hypotheses indicates expected increases based on an independent variable? Directional hypothesis Non-directional hypothesis
A researcher ran an analysis to understand if corporate culture was related to business revenue. He sampled local small business representative of all small businesses in the nation. He measured Q1 revenue of the businesses. Then he deployed a training for corporate culture. The next year, he measured Q1 revenue again. He ran an analysis in Microsoft Excel: \( t \) - Test: Paired Two Sample for Means. From the data output, he failed to reject the null hypothesis. What conclusion can the researcher determine? The patterns he saw in his small sample cannot be inferred to the population. The patterns he saw in his small sample can be inferred to the population.
If you have a study design that requires a single sample exposed to different levels of the independent variable, what sort of test might you consider? Independent samples test Matched samples test
In independent sample tests, what is the best way to ensure equivalence between samples? Convenience Random assignment Different levels of the independent variable
A local teacher wants to see if teaching writing in different ways impacts student learning. She has two classes of similar characteristics. In one class, she will use Teaching Strategy A and in the other class she will use Teaching Strategy B. She ran her analysis in Microsoft Excel and received the following output table. If the P value is less than \( 0.05 \), the null hypothesis may be rejected. Based on the data table, what decision should the teacher make about the hypothesis? A She should fail to reject the null hypothesis. (B) She does not have enough information to decide. C She should reject the null hypothesis. She should accept the null hypothesis.
