Research has suggested that breakfast is the most important meal of the day. A nutritionist randomly selects 100 individuals and asks them: “Did you have breakfast this morning? Yes or no?”

(a) What is an appropriate method for graphing the data?

For this situation, the use of pie chart or bar graph is an appropriate method for graphing the given data.

(b) Why is it appropriate?

For this scenario, the pie chart is an appropriate method for graphing the data, because there are only two types of responses such as ‘yes’ or ‘no’, so we can show it very nicely in pie chart. If there are limited number of categories say five or less, then we can use pie chart effectively. If categories are large in number then pie chart is not good enough.

2. A pet store owner is interested in the number of pets owned by her customers. She takes a random sample of 100 customers and asks them: “How many pets do you own?”

(a) What is an appropriate method for graphing the data?

For this scenario, the frequency histogram or bar graph is an appropriate method for graphing the data.

(b) Why is it appropriate?

The frequency histogram or bar graph is appropriate here because the variable number of variables can take the values from 0 to n. This means we would have frequency distribution for the number of pets own by the respondents. So, we can arrange this data by using frequency histogram or bar graph.
