Overview: In this activity you will again practice analyzing the distributions of quantitative variables using descriptions of shape, center and spread. This is the same type of thinking you did in 2.1.1 with dot plots, but this time the data will be summarized in a histogram. 1) Match the following descriptions to the histograms I-Il. A. Scores on an easy exam for a class of students B. Scores on a hard exam for a class of students C. Number of siblings for a large sample of U.S. adults D. Exact volume of soda in a one-liter bottle for a case of 24 bottles E. Dates on the pennies I have in my car ashtray F. Weights for a large sample of newborn babies
Explanation / Answer
a)Score on easy exam should be more - Thus, histogram I (more values at right)
b)Score on tough exam should be low - Thus, histogram II (more values at left)
c)Number of siblings for a large sample of US adults. Assuming normal distribution Histogram III
d) Exact volume of soda in one liter soda bottle for case of 24 bottles
Has to be normal distribution with less standard deviation of form Histogram III
e)Dates on pennies, has to be old so Histogram I (more values towards left)
f)weights of sample of newborn babies
Has to be normally distributed.Thus, histogram III
