![]() A large t-score tells you that the groups are different.When you run a t test, the bigger the t-value, the more likely it is that the results are repeatable. A t score of 3 means that the groups are three times as different from each other as they are within each other. The smaller the t score, the more similarity there is between groups. ![]() The larger the t score, the more difference there is between groups. The t score is a ratio between the difference between two groups and the difference within the groups. This assignment is an example of the basic statistical analyses using descriptive statistics (mean, median and mode) and a t-test. Software such as Excel provides these basic statistics in easy-to-learn procedures. Most beginner evaluators and researchers conduct basic descriptive and inferential statistics for their analyses.

Interestingly during the third and fourth 2 h blocks of these frequent meal conditions, there was a decrease in the insulin AUC (0700–0900 > 1100–1300 p = 0.004 0700–0900 > 1300–1500 p = 0.015 Fig. 3b), compared to the initial 2 h block.Grading Basis: Each of the seven (7) questions/calculations are worth 14 points each out of 100 possible points. Finally, when comparing the 2 h net AUC values between the 6CHO and 6HP conditions, we observed a main effect for condition, such that the 6CHO treatment resulted in higher blood glucose levels than 6HP ( p = 0.004 Fig. 3a), paralleled by a lower insulin response during the 6HP condition ( p = 0.012 vs. The 6HP condition had the smallest insulin response to meal ingestion ( p = 0.018 vs. ![]() When divided into 4 h blocks, glucose AUC was higher in the 6CHO condition ( p = 0.026) compared to the 3CHO condition, although no difference was found in the insulin values. Similarly, the 12-hour insulin AUC in the 6CHO condition resulted in a lower insulin release than the isocaloric 3CHO condition ( p = 0.05). These subjects demonstrated significantly increased blood glucose levels during the 6CHO (710.0 ± 251.0 mmol/L∗min) compared to both the 3CHO (522.7 ± 99.3 mmol/L∗min p = 0.029) and 6HP (442.1 ± 121.0 mmol/L∗min p = 0.008) meal conditions when assessed as 12 h AUC ( Fig. 2a). The pattern of response for glucose and insulin levels is in Fig. 1. walking to restroom).īaseline glucose and insulin values were similar across the three study days. All of the subjects participated in quiet, sedentary activities including reading, studying, and watching movies, with minor physical activity (e.g. The additional protein added in this condition consisted of Pro Complex whey protein and branched-chain amino acids which also contains a small amount of fat (∼2 g) sufficient to balance the fat component of the dietary conditions at 20% (Pro Complex, Optimum Nutrition Inc., Aurora, IL, USA). ![]() The high-protein condition (45% PRO, 35% CHO, 20% FAT) was consumed as 6 meals (6HP ∼1046 kJ/meal), over the 12-h period. Wegmans Nutritional Beverage (Wegmans, Rochester, NY, USA) was used for this study and consisted primarily of sucrose and corn syrup (CHO), soy, and whey (PRO). The energy-matched meal conditions consisted of 6276 kJ (15% protein (PRO), 65% carbohydrate (CHO), 20% fat (FAT)), consumed in evenly spaced intervals as either 3 large meals (3CHO ∼2093 kJ/meal) or 6 small meals (6CHO ∼1046 kJ/meal).
