Statistics

Experimental probability that is responsible for converting raw data into Distribution.

Concepts

• Raw Data
• Random Variable
• Sample
• Population
• Parameters vs Statistics

Displaying

• Frequency Table - convenient overview of the distribution of values of the variables
• Histogram - bar graph with no gaps but the area of the bars are proportional to frequencies of the values of the variable
• Relative Frequency - same information as histogram/bar graph but as a line graph.
• Cumulative Frequency - cumulative version of frequency. used for niche situations

Tendencies

• Measurements of Central Tendencies
• Skewed Distribution
• Grouped Data
• Weighted Means
• Modal Interval

Sampling

• Sampling Techniques
• Biases

Experiments

• Types of Experiments
• Experimental Study Prerequisites
• Experiment Cases
• Primary vs Secondary Data
• Surveys

Measures of Spread

• Measures of Spread
• Percentile Examples
• Quartiles
• Non-Symmetrical Quartiles
• Outliers
• Quartile Examples
• Standard Deviation
• Variance
