Welcome to the section on Statistics Fundamentals. This course will provide you with a comprehensive understanding of the basics of statistics, including descriptive statistics, probability, and inferential statistics.
Key Topics
Descriptive Statistics
Descriptive statistics is the branch of statistics that describes the features of a dataset. This includes measures such as mean, median, mode, range, variance, and standard deviation.
- Mean: The average value of a dataset.
- Median: The middle value of a dataset when it is ordered from smallest to largest.
- Mode: The most frequently occurring value in a dataset.

Probability
Probability is the measure of the likelihood that an event will occur. It is expressed as a number between 0 and 1, where 0 indicates impossibility and 1 indicates certainty.
- Discrete Probability: The probability of a specific outcome in a discrete random variable.
- Continuous Probability: The probability of an outcome falling within a certain range in a continuous random variable.

Inferential Statistics
Inferential statistics is the branch of statistics that uses data from a sample to make inferences about the population from which the sample was drawn.
- Hypothesis Testing: The process of testing a claim about a population parameter based on a sample.
- Confidence Intervals: A range of values that is likely to include the true population parameter.
