Two groups of students were tested to compare thir speed working math problems Each group was given the same problems.One group used calculators and the other group computed without calculators?

The independent variable in this study is the use of calculators, while the dependent variable is the speed of solving math problems. By comparing the two groups, researchers can determine if the use of calculators has an impact on the speed of problem-solving. To analyze the results, statistical tests such as a t-test or ANOVA can be used to determine if there is a significant difference in speed between the two groups.
