What is an independent variable.

What is the liquid (cola).
When you see a measurement, the last place value is always
What is estimated.
This type of observation is measureable.
What is Quantitative Measurement.
Will putting my plant in the closet will decrease its chance of living? What is wrong with this hypothesis?
What is...it is written as a question. It must be written as a prediction sentence.
This is the variable we measure to see if the IV affected it.
What is the Dependent Variable.
If I water a plant with cola then it will grow taller. What is the DV?
What is height.
How close a measurement is to the true value is the definition of
What is accuracy.
If you drink more milk will you get stronger bones? State a good hypothesis for this question.
What is...If you increase the amount of milk you drink, then you will increase the strength of your bones.
Which variable is placed on the y-axis of a graph?

How close a series of measurements are to one another is a definition for
What is precise or precision.
What variable is placed on the x-axis?

List the independent and dependent variables in the following hypothesis. If soil temperatures rise, then plant growth will increase.
What is...IV-soil temperatures, DV-plant growth.
