Illustrates the use of the hypothesis testing procedure to compare 2 samples in terms of their mean scores. This was done several times because different kinds of groups were compared (males vs. females); those who experienced severe trauma vs. those who experienced mild trauma) and because comparisons were made on 8 variables of interest.
Illustrates (1) the use of the term "two-tailed" to indicate a nondirectional alternative hypothesis, (2) the use of the word "alpha" to represent the phrase "level of significance," and (3) the use of the symbolic statement "p<.05" to indicate that the null hypothesis was rejected. (See the last sentence of the "Method" section, the first sentence of the "Results" section, and the Note beneath Table 1.)
In this study, the hypothesis testing procedure is used to compare two groups of undergraduate college students who underwent two different methods of instruction. Includes these terms: "level of significance," "alpha," "alpha level," "significant," "not statistically significant," "p<0.05," and "p>0.05." Also presented are the tests' calculated values. (See the second sentence in the section entitled "Research Design" and the 4th, 6th, and 8th paragraphs of "Results.")
Illustrates the rarely seen words "the null hypothesis was rejected." (See the second sentence in second paragraph of "Findings" and the third sentence of the fourth paragraph of this same section.)
