Here are some summary statistics for the size of forest fires last year: smallest fire = 74 acres, mean =451\text { mean } = 451 mean =451 acres, median =451\text { median } = 451 median =451 acres, range =7926\text { range } = 7926 range =7926 acres, IQR=387\mathrm { IQR } = 387IQR=387 Q1=180,Q 1 = 180 ,Q1=180, standard deviation = 61 acres.Is the distribution symmetric,skewed to the left,or skewed to the right? Explain.
A) Skewed to the right; mean higher than median.
B) Symmetric; mean same as median.
C) Skewed to the left; mean higher than median.
D) Skewed to the right; mean lower than median.
E) Skewed to the left; mean lower than median.
Standard Deviation
A numerical indicator that calculates the degree of spread or variability among a series of data points.
Mean
A statistical measure defined as the sum of all values in a data set divided by the number of values, representing the average.
Median
The middle value in a sorted list of numbers, effectively dividing the dataset into two equal halves.
- Determine and explicate the outlines of data distributions, encompassing symmetric, shift left, and shift right.
- Explore the association between median and mean in discerning the skewness of distribution patterns.
