What is the dependent variable (what is being measured by the data)?
gas mileage
number of dimples
speed
The dependent variable in this context is gas mileage.
The dependent variable, or what is being measured by the data, can vary depending on the context of the study. In the case of your examples:
1. Gas mileage: The dependent variable would typically be the miles per gallon (MPG) achieved by a vehicle. This can be measured by collecting data on the distance traveled and the amount of fuel consumed.
2. Number of dimples: The dependent variable would be the count or quantity of dimples observed. This could relate to objects such as golf balls, where the number of dimples could potentially affect their performance.
3. Speed: The dependent variable would be the velocity or rate of motion. This can be measured by recording the distance traveled over a given period of time.
It's important to note that the specific dependent variable will depend on the research question or hypothesis being investigated.
