Refer to the following excerpt from a hypothetical research article thatcompared memory test performance between two groups of participants:those who consumed a caffeinated beverage before the test and thosewho consumed a non-caffeinated beverage:
An independent samples t-test was conducted to examine thedifference between experimental conditions on testperformance. The results indicated a significant differencebetween participants who consumed the caffeinated beverageand participants who did not, with participants in the caffeinatedgroup (M = 7.64, SD = 2.41) performing worse than participantsin the non-caffeinated group (M = 9.81, SD = 3.16), t(97) =2.14, p < .05.
Write a brief paper explaining what the author means when she says thatthe results were statistically significant. In other words, what does itmean to say that results are statistically significant? Be sure to explainwhat a p value is and how it relates to statistical significance.
As a reminder, M stands for mean, SD stands for standard deviation, thet indicates that this was a t-test, and the p represents the p value. Youcan refer to page 353 of your textbook, Discovering Statistics Using IBMSPSS Statistics, for help interpreting the statistical results listed in theexcerpt, but that may not be necessary.
