Description
1) Find a study where the distribution follows a normal or bell-shaped curve. An example of a normal distribution or bell-shaped curve, called “Heights of Red Pine Seedlings”, is located in the beginning of Chapter 6 in the book. Cite the source of the study you’ve selected, and explain why you think the distribution is bell shaped. For instance, if the study is about income, then the income may be low for a child and peak at age forty-five and then gradually drop. Respond to at least two of your classmates’ posts.

of the population as a result of variation in risk factors such as overweight, cardiovascular risk,
among another factor. For example, the value of prevalence of obesity will be high when the risk
factor increases. Similarly, the increase in the prevalence of adult obe...
