A research firm created a survey asking city residents about building a new city park. The firm will compile the results and create a report. The firm wants to compare the number of people who support the new park to the total number who completed the survey. Which type of calculated figure should the report contain?

To compare the number of survey respondents who support the park with the total number who completed the survey, calculate the supporting respondents as a share of the total. Expressing that share as a percentage makes the comparison clear. A sum or grand total only adds numbers, while a running sum tracks a cumulative total.
