Question

Does drinking caffeine affect students’ performance on tests? Step 2: Create hypotheses statements for the research question you chose. Step 3: In at least 10 or more sentences, describe how a researcher may collect and analyze the data for the research question you chose.

Answer 1

Step 2:

H0: Null Hypothesis: Drinking caffeine does not affect students' performance

HA: Alternative Hypothesis: Drinking caffeine affects students' performance

Step 3:

Through Simple Random Sampling technique, identify the sample of n students for the research analysis.

Collect from each of the n students the following details:

For i = 1, 2,...n:

x_i = Number of coffee cups drunk per day over a specific period of time by the i^th student

y_i = Performance on tests over the same period by the i^th student

Tabulate the values of (x_i, y_i)

Conduct detailed Data Reduction and Analysis of above data through graphs (bar chart, pie diagram etc., ) and Charts, Measures of Central Tendency, Dispersion etc.

Statistically analyze the relation between x and y through Correlation and Regression Analysis.

Conduct Hypothesis test on the relation between x and y

Make correct generalization through proper statistical methods and finalize the conclusions of the research activity.
