Bar graphs of maximal hand grip force, including different subsets of students who participated in the study. This graph displays the statistical comparison between the student’s hand force calculated in 4 different ways: (A) only the 12 students who completed the 4 data point measurements are included, and the single highest maximum point of 3 hand grips trial measurements is taken in this comparison (n = 12, time of the day p = 0.9817, stress/exam levels p = 0.5634, 2-way ANOVA, GraphPad Prism); (B) only the 12 students who completed the 4 data point measurements are included, and an average of the highest maximum point of 3 hand grips trial measurements is taken in this comparison (n = 12, time of the day p = 0.9914, stress/exam levels p = 0.8812, 2-way ANOVA, GraphPad Prism); (C) all 21 students are included, and the single highest maximum point of 3 hand grips trial measurements is taken in this comparison (n = 21, time of the day p = 0.9948, stress/exam levels p = 0.3130, 2-way ANOVA, GraphPad Prism) and (D) all 21 students are included, and an average of the highest maximum point of 3 hand grips trial measurements is taken in this comparison n (n = 21, time of the day p = 0.9752, stress/exam levels p = 0.6785, 2-way ANOVA, GraphPad Prism). The y-axis displays the single maximum (Max) or the average of 3 trials (Avg) in Newtons, and the x-axis displays the time of day and stress level of the day. Each circle and triangle represents an individual data point plotted.
