A researcher is studying the relationship between sugar consumption and weight gain. Twelve volunteers were randomly assigned to one of two groups. The first group had five participants which were put on a diet low in sugar and the other group with the remaining seven participants received 10% of their calories from sugar. After 8 weeks, weight gain was recorded from each participant. a) Explanatory variable: (weight, 10% calories, Sugar consumption, weight gain) b) Response variable: (weight gain, type of diet for severe participants, sugar consumption) c) Which of the following principles was not used in this study? A. Replication B. Blinding C. Randomization D. Control d) This study is a(n) (Survey, observational, experimental) study. e) The ‘low sugar’ group can be thought of as a control group. The control group is being used in this experiment to avoid (republication, confounding with the 100% sugar group, placebo pills, nonresponse bias)
