Understand your data distribution and characteristics

Measures of Central Tendency:

Mean (Average): Sum of all values divided by count

Median: Middle value when data is sorted

Mode: Most frequently occurring value(s)

Each measure provides different insights into data center

Measures of Dispersion:

Range: Difference between maximum and minimum values

Variance: Average of squared differences from mean

Standard Deviation: Square root of variance

These measure how spread out the data is

Common Examples:

Normal Distribution: Mean ≈ Median ≈ Mode

Skewed Right: Mean > Median > Mode

Skewed Left: Mean < Median < Mode

Bimodal: Two distinct modes in the data

Real-World Applications:

Business: Sales analysis, customer behavior, quality control

Science: Experimental results, measurement analysis

Education: Test scores, student performance analysis

Finance: Investment returns, risk assessment

Statistical Insights:

Mean is sensitive to outliers in the data

Median is robust to outliers and skewed distributions

Mode identifies the most common values in the dataset

Standard deviation indicates data variability around the mean
