ALL QUESTIONS CORRECTLY!!! 1.) Physical therapists use an outcome measure called the Berg Balance Scale. This scale has multiple test items related to balance. Items are scored on a 0 to 4 scale, with a total possible score of 56. Here is an example of an item: Sitting to Standing -Instructions: "Please stand up. Try not to use your hands for support." 4 - able to stand without using hands and stabilize independently 3 - able to stand independently using hands 2 - able to stand using hands after several tries 1 - needs minimal aid to stand or stabilize 0 - needs moderate or maximal assist to stand The data from the Berg Balance Scale is an example of which of the following types of data? A.) interval B.) nominal C.) Ordinal D.) Ratio 2.) Physical therapists use an outcome measure called the Berg Balance Scale.The Berg Balance Scale has high interrater reliability. What does this mean? A.) This scoring can be reproduced accurately by multiple raters B.) This scoring can be reproduced multiple times by the same rater C.) This test does an excellent job of measuring balance D.) This test requires multiple raters before it generates accurate results. 3.) Given the following scores for the Berg Balance Scale: 32, 23, 15, 49, 44, the value of 32 represents which of the following measures of central tendency: Group of answer choices A.) mean B.) median C.) mode D.) standard deviation 4.) The Six Minute Walk test measures the distance an individual is able to walk in a 6 minute time period and is recorded as number of feet or meters. This data is an example of which of the following types of data? Group of answer choices A.) interval B.) ordinal C.)nominal D.) ratio 5.) A researcher wants to study the effects of a low carbohydrate diet on weight loss in adults. What is the independent variable? A.)Age B.) Low carbohydrate diet C.)Weight loss D.) Adults 6.) A researcher wants to study the effects of a low carbohydrate diet on weight loss in adults. What is the dependent variable? A.) Age B.) Low carbohydrate diet C.)Weight loss D.) Women 7.) A researcher wants to study the effects of a low carbohydrate diet on weight loss in adults. What is a possible covariate in this study? A.) Age B.) Low carbohydrate diet C.) Weight loss D.) Women 8.) A researcher concluded that individuals with hypertension who took an investigative blood pressure medication had a blood pressure 20% lower than the control group who took a placebo pill. Their statistical analysis resulted in a p value equal to .03. How do you interpret this? A.) The results are significant. Accept the null hypothesis. There is a 3% probability that the results were due to chance. B.) The results are not significant. Accept the null hypothesis. There is a 97% probability that the results were due to chance. C.) The results are significant. Reject the null hypothesis. There is a 3% probability the results were due to chance. D.) The results are not significant. Reject the null hypothesis. There is a 97% probability the results were due to chance
