The music teacher divided students into two groups for one month one group listened to classical music, the other group was told to not listen to classical music at all. At the end of the month, all children were given a reading comprehension test.
What is the independent variable? What is the dependent variable?
Independent variable: What music the students listened to.
Dependent variable: The numerical grades on the reading comprehension test.

Explain what the difference between quantitative and qualitative data is and provide an example for each...
Quantitative Data: measures of values or counts and are expressed as numbers.
ex. mass of solution is 2.8 g
Qualitative data: measures of 'types' and may be represented by a name, symbol, or a number code.
ex. solution is cloudy
ex.
