Farrah is designing an experiment in an effort to determine how the environment noise level people are exposed to affects their hearing. In the experiment, Farrah is collecting these data by researching the average number of decibels a person is exposed to in a day, using their smartphones. She is then testing each participant’s hearing level with a hearing test and giving them a score from 1-100.
The participant’s age
The score on the hearing test
The number of day the experiment lasts
The average decibels a person is exposed to daily.
The data that Farrah should collect in her experiment are:
- The participant's age
- The score on the hearing test
- The number of days the experiment lasts
- The average number of decibels a person is exposed to daily.
