Central Tendency and Data Analysis

The video tutorial covers central tendency concepts, including mean, median, mode, and range. It provides examples of word problems to illustrate how to calculate these measures and how they change when data is adjusted. The tutorial also discusses the impact of outliers and how to determine required scores to achieve specific averages or medians.
