{
"text": "Step four: Count how many times each time appears in your data, and place a dot above each one. There are two people who spent one-fourth of an hour on homework, so you put two dots above one-fourth on the line. Four people spent one-half hour, so you put four dots above one-half. Two students spent three-fourths of an hour, so you put two dots above three-fourths. And one student spent a full hour \u2014 so one dot goes above one.",
