• The independent variable is the variable that is being measured or tested in an experiment.

• The dependent variable is the variable that is being measured or tested in an experiment.

• The dependent variable is the variable that remains constant in an experiment.

• The dependent variable is the variable that is manipulated in an experiment.

What is the independent variable in a given experiment?

• The variable that is changed or manipulated

Explain the concept of range in data distribution.

• The range is the difference between the highest and lowest values in a dataset.

• The range is the median of the values in a dataset.

• The range is the average of all the values in a dataset.

• The range is the mode of the values in a dataset.

What is the difference between mean and median?

• The mean is the highest number in a set, while the median is the lowest number in a set.

• The mean is the middle number in a set, while the median is the average of a set of numbers.

• The mean is the sum of all numbers in a set, while the median is the difference between the highest and lowest numbers.

• The mean is the average of a set of numbers, while the median is the middle number in a set of numbers when they are arranged in order.
