A survey designed by their teacher was completed by students in a high school statistics class.

02

 Step 2.make a number line for each piece of data Put a dot on the number line above the corresponding number.

03

 Step 3. The shape of the distribution.  

The peak in the dotplot is roughly in the middle of the graph, indicating that the distribution is roughly symmetric.

We notice that the distribution has a single peak at 7, and there appear to be no gaps in the dotplot.

Roughly symmetric

Single peak

No gaps

Risks of playing soccer (1.1) A study in Sweden looked at former elite soccer players, people who had played soccer but not at the elite level, and people of the same age who did not play soccer. Here is a two-way table that classifies these individuals by whether or not they had arthritis of the hip or knee by their mid-fifties:

Part (a). What percent of the people in this study were elite soccer players? What percent of the people in this study developed arthritis?

Part (b). What percent of the elite soccer players developed arthritis? What percent of those who got arthritis were elite soccer players?

Part (c). Researchers suspected that the more serious soccer players were more likely to develop arthritis later in life. Do the data confirm this suspicion? Calculate appropriate percentages to support your answer.

Far from home A survey asked first-year college students, 鈥淗ow many miles is this college from your permanent home?鈥 Students had to choose from the following options: 5 or fewer, 6 to 10, 11 to 50, 51 to 100, 101 to 500, or more than 500. The side-by-side bar graph shows the percentage of students at public and private 4-year colleges who chose each option. Write a few sentences comparing the distributions of distance from home for students from private and public 4-year colleges who completed the survey.

Healthy streams Nitrates are organic compounds that are a main ingredient in fertilizers. When those fertilizers run off into streams, the nitrates can have a toxic effect on fish. An ecologist studying nitrate pollution in two streams measures nitrate concentrations at 42 places on Stony Brook and 42 places on Mill Brook. The parallel dotplots display the data. Compare the distributions of nitrate concentration in these two streams.

Medical study variables Data from a medical study contain values of many variables for each subject in the study. Some of the variables recorded were gender (female or male); age (years); race (Asian, Black, White, or other); smoker (yes or no); systolic blood pressure (millimeters of mercury); level of calcium in the blood (micrograms per milliliter). Classify each variable as categorical or quantitative.
