What is necessary to choose when analyzing results in statistical analyses?

• The correct mathematical equations

• The type of graph to use

• A statistical analysis based on the hypotheses you are looking to test

• The sample size for the study

What will not be covered in the learning material regarding statistical analyses?

• How to choose the appropriate analysis

• The math behind the analyses

• The hypotheses that need to be tested

• The results of the analyses

What is the purpose of paired samples t-tests?

• To compare two different samples from different populations

• To compare two means on the same scale using the same sample of participants

• To compare the variance between two different groups

• To determine the correlation between two variables

In which research design is paired samples t-tests most typically seen?

• Cross-sectional studies

• Longitudinal studies

• Pre-test post-test research design

• Experimental studies with control groups

Which of the following is an example of a situation where a paired samples t-test might be used?

• Comparing the average income levels of two different cities

• Determining if a new teaching method improves student performance over the old method

• Assessing the effectiveness of a drug by comparing patient health before and after treatment

• Measuring the impact of a social media campaign on brand awareness

What does an Independent-Samples Design in research typically compare?

• Two related or dependent samples

• Two separate or independent samples

• Multiple variables within a single sample

• The same sample under different conditions

Which of the following is an example of what an Independent-Samples Design might test for mean differences between?

• Two distinct populations

• Two treatment conditions

• The same population before and after a treatment

• Multiple treatments within the same population

What is another example of what an Independent-Samples Design might test for mean differences between?

• The same population under varying environmental conditions

• Two treatment conditions

• One population with different demographic characteristics

• The same treatment applied at different times

What is the purpose of conducting a One-Way ANOVA test?

• To compare two group means

• To compare means of three or more groups

• To calculate the median of a single group

• To determine the mode of multiple groups

What does the null hypothesis in a One-Way ANOVA test typically state?

• All groups have different means

• All groups have an identical median

• All groups have an identical mean

• No groups have an identical mode
