Two groups of students were timed to compare how fast they could complete a set of math problems. Each group was given the same problems. One group used calculators. The other group did not use calculators.
IV: using or not using calculators
DV: amount of problems solved correctly
CV: same math problems
Which one of the variables was identified INCORRECTLY?
The DV is wrong. Here is what it should be: the time it takes to complete the problems
The IV is wrong. Here is what it should be: boys versus girls
The CV is wrong. Here is what it should be: same amount of time for all students
Students of different ages were given the same puzzle to put together. The time it took each student to complete the puzzle was compared.
IV: boy or girl students
DV: time it took to complete the puzzle
CV: same puzzle
Which one of the variables was identified INCORRECTLY?
The CV is wrong. Here is what it should be: age of students
The DV is wrong. Here is what it should be: the size of the puzzle
The IV is wrong. Here is what it should be: age of the students
Select the correct hypothesis for the following variables.
Research Question: Does salt water freeze faster than fresh water?
Independent Variable: type of water (salt water or fresh water)
Dependent Variable: time it takes water to freeze
If salt water freezes faster than fresh water, then I will test salt water and fresh water.
If I test salt water and fresh water, then salt water will freeze faster.
If I test salt water and it freezes, then I will test fresh water.
