Document Summary
Include new information into our understanding of the world. Used descriptive statistics (mean, standard deviation, histogram, and inferential statistics: report findings: 0. 44 > 0. 05. No evidence to support the hypothesis: revise theory: diet during studying may not significantly affect test performance. Testing hypotheses: anecdotal evidence- evidence gathered from others or self-experience, cannot solely rely on anecdotal evidence, a single experience is not always representative of the general result that would occur if you drank the energy drink several times. The independent variable is manipulated across 2 groups of participants: confounding variable- a variable other than the independent variable that effects the results. Measures of variability: standard deviation- a measure of the average distance of each data point from the mean, smaller spread = smaller standard deviation, larger spread = larger standard deviation. The t-test reveals the probability of getting the results he found. Less than 5% probability of obtaining the data: statistically not significant- p > 0. 05.
