7. Two groups of subjects were divided in an experimental study. One group was given a drug to help speed up
their metabolism and result in weight loss. The other group was given a placebo (a pill that looks identical
to the one given to the other group, but without the weight loss drug). After a month of the experiment, the
weight loss of each individual in each of the two groups were measured. In general, people in the group who
took the metabolism drug did lose more weight, although there were differences in the amount each lost.
There are two main types of variability occurring in this study. Describe each type below in the context of
this study
Induced Variability
Natural Variability

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
