What is the difference between probability and likelihood?

• Probability and likelihood are interchangeable terms.

• Probability is based on all possible outcomes, while likelihood is based on observed data.

• Probability is based on observed data, while likelihood is based on all possible outcomes.

• Probability is used in statistics, while likelihood is used in machine learning.

Explain the concept of standard deviation in statistics.

• Standard deviation is the same as mean

• Standard deviation measures the central tendency of data

• Standard deviation is used to calculate the median

• Standard deviation in statistics is a measure of the amount of variation or dispersion of a set of values.

How is the range calculated in statistics?

• Range = Maximum Value + Minimum Value

• Range = Maximum Value * Minimum Value

• Range = Maximum Value / Minimum Value
