Difference between quantitative and qualitative data?
Quantitative data has do with observations without specific numbers. Qualitative data has to do with numbers and measurements.
Quantitative data has to do with numbers and measurements. Qualitative data has to do with observations without specific numbers.
Quantitative data has to do with only a selected few objects. Qualitative data has to with what quality the object is in in order to be tested.
Quantitative data measures how acidic a solution is. Qualitative data measures how basic a solution is.
What makes a solution?

What is the difference between independent and dependent variables?
Independent variables are the variables changed in the experiment, whereas the dependent variables are the results of that change.
Independent variables are parts of the experiment's environment (like pH or temperature) but have not relation to the experiment, dependent variables are a part of the experiment.
Independent variables are not experimented on in an experiment, and dependent variables are experiment on in an experiment
