This study found a null effect (no impact of sucrose on children's behavior). There were only 48 children in the diet study, and this might be considered a low number--there may not have been enough kids in the study to detect a small effect of sucrose. However, the repeated measures design means this study can make a stronger case for the conclusion that sugar doesn't affect kids' behavior. Explain why the repeated measures design helps support the conclusion. Instructions: Using the following information and prompts from your textbook author's blog, readthrough the information provided and then as a group, determine the best responses.Here's something "everybody says": Kids will become hyperactive if they eat too much sugar. This folkbelief is as much a part of North American cultural wisdom as learning styles and the catharsishypothesis. But this column in the New York Times explains that, like learning styles and catharsis, theidea of a "sugar high" is also a myth.The physician who wrote the column traced the modern idea of sugar causing hyperactivity to 1975. Butthen the author describes a randomized clinical trial on this question. Here's the description:An extraordinarily rigorous study settled the question in 1994. Writing in the New EnglandJournal of Medicine, a group of scientists tested normal preschoolers and children whose parentsdescribed them as being sensitive to sugar. Neither the parents, the children nor the researchstaff knew which of the children were getting sugary foods and which were getting a dietsweetened with aspartame and other artificial sweeteners. Urine was tested to verify compliancewith the diets. Nine different measures of cognitive and behavioral performance were assessed,with measurements taken at five-second intervals.The original study was, indeed, ambitious. The authors provided all food to the homes of the children inthe study so they could completely control what sweeteners were being used. The study took place overnine weeks in a repeated-measures design--the diets were based on sucrose (sugar) one week, aspartameanother week, and saccharine during another week. The researchers measured the children's cognitiveperformance and mood throughout the study.The study concluded that sugar does not affect children's behavior or cognitive function.An editorial that accompanied the study put a fine point on that conclusion, stating "there is noevidence that sugar alone can turn a child with normal attention into a hyperactive child."

Given : This study found a null effect (no impact of sucrose on children's behavior). There were only 48 children in the diet study, and this might be considered a low number--there may not have been enough kids in the study to detect a small effect of sucrose. However, the repeated measures design means this study can make a stronger case for the conclusion that sugar doesn't affect kids' behavior. In a repeated measures design , we record the data for the same subject in every conditionIt is given that this study found a null effect (no impact of sucrose on children's behavior) , a repeated measures design will enable us to conclude that our results is not happened due to some error as we have data points over a period of time repeatedly taken. A repeated measures design helps us to reduce the variability in our result to minimum as the validity of the data will be very high (we have recorded the data with repeated measures , if some error occurred in some measurement for a subject, we have multiple measurement for the same subject which will help us in reducing the variability and concluding our results in a better way with more conviction) .If we have small sample size, a repeated measure study helps us in reducing he variability with more data validity.
