2.7: Skewness and the Mean, Median, and Mode

WebThe mean (or average) is the most popular and well known measure of central tendency. It can be used with both discrete and continuous data, although its use is most often with continuous data (see our Types of Variable guide for data types). WebOct 3, 2024 · Step 1: Sketch a normal distribution with a mean of μ=30 lbs and a standard deviation of σ = 5 lbs. Step 2: A weight of 35 lbs is one standard deviation above the mean. Add the percentages above that point in the normal distribution. 13.5% + 2.35% + 0.15% = 16%. Step 3: Since there are 200 otters in the colony, 16% of 200 = 0.16 * 200 = 32.
