It yieldsa value of p, which indicates the probability that chance or random sampling errors created the dif-ference between the means. Most researchers declare a difference to be significant when p is equal toor less than .05. The lower the probability, the more significant the difference. Thus, a p of .01 ismore significant than a p of .05. When a researcher declares a difference to be statistically signifi-cant, he or she is rejecting the null hypothesis. The lower the probability, the more confidence a re-searcher can have in rejecting the null hypothesis.Note that the absence of footnotes with probabilities in a table that contains a number of sig-nificance tests indicates that the comparison in question is not statistically significant.Excerpt from the Research Article'The married sample comprised members of 100 heterosexual couples (54% were women and46% were men) from a Midwestern university. The dating sample also consisted of members of 100heterosexual couples (59% were women and 41% were men) from the same Midwestern university.All the married and dating couples were Euro-American. A researcher selected subjects in a haphaz-ard fashion and asked them to complete a short survey.... The mean age of the sample was 26.7years (SD = 2.6).The Affectionate Communication Index is a 19-item index that...assesses the amount of ver-bal and nonverbal affectionate communication and support on a 7-point...scale, with anchors of 1 =partners always engage in this type of affectionate activity to 7 = partners never engage in this typeof activity. [Thus, lower scores indicate more affectionate communication. Table 1 shows the resultsfor the nonverbal activities.]Table 1Dating and Married Individuals' Reports of Nonverbal Affectionate CommunicationItemMSDntHold handsDating1003.71.93.3*Married1002.91.7Kiss on the lipsDating1002.91.54.9*Married1002.01.1Kiss on the cheeksDating1003.61.64.5tMarried1002.71.3Give massages to each otherDating1004.21.85.0*Married992.51.8Put arm around shoulderDating1003.61.84.6*Married922.51.5Table 1 continued on next page →'Source: Punyanunt-Carter, N.
