A. The five concepts of univariate analysis are: 1. Central Tendency: Measures like mean, median, and mode to understand the center of the data distribution. 2. Dispersion: Measures such as range, variance, and standard deviation to assess the spread or variability of the data. 3. Distribution: Understanding the shape of the data through histograms, box plots, and probability plots. 4. Outliers: Identification and treatment of extreme values that deviate significantly from the rest of the data. 5. Summary Statistics: Providing a concise overview of the data through quantiles, percentiles, and other statistical measures.
