What are the variables in qualitative research?

A qualitative variable, also called a categorical variable, is a variable that isn't numerical. It describes data that fits into categories. For example: Eye colors (variables include: blue, green, brown, hazel). States (variables include: Florida, New Jersey, Washington).

Is pH a dependent variable?

For an experiment where the pH is measured for different solutions, the pH is the dependent variable. The solutions are the independent variable. You could have many controlled variables, one is the pH paper used for the measurements.

What is the independent variable in a titration?

Titrations are often recorded on titration curves, whose compositions are generally identical: the independent variable is the volume of the titrant, while the dependent variable is the pH of the solution (which changes depending on the composition of the two solutions).

What is the dependent variable when the pH level is constant?

The factors that remain constant are called the control variables. Control variables allow you to conclude that the results on enzyme activity obtained in your experiment are due to the varying of pH, the independent variable.

How do you do a pH experiment?

You can also make your own pH indicator—use a blender to mix one part chopped red cabbage with two parts boiling water and use the juice to test different solutions. Acids will turn the pigments in the indicator to a reddish color; bases will turn the pigments bluish or yellow-green.

What two variables affect an enzyme?

Factors affecting enzyme activity Enzyme activity can be affected by a variety of factors, such as temperature, pH, and concentration. Enzymes work best within specific temperature and pH ranges, and sub-optimal conditions can cause an enzyme to lose its ability to bind to a substrate.

What are two variables that affect the rate of enzymes?

Several factors affect the rate at which enzymatic reactions proceed - temperature, pH, enzyme concentration, substrate concentration, and the presence of any inhibitors or activators.
