What measure of spread is used when your data distribution is symmetrical?
Answer: When the data distribution is symmetrical, the appropriate measure of spread is standard deviation. The reason is both sides of symmetrical distribution will have same spread.
Symmetrical distribution: Symmetrical distribution is one when both sides of the distribution are identical. The symmetrical distribution is bell shaped and mean, median and mode are equal in symmetrical distribution.
Standard deviation: Standard deviation is the measure of dispersion. It measures the deviation of a set of numbers from its mean. It is defined as the square root of means of the squared deviations from the arithmetic mean
Yes,2 is the right answer.
So the scale in part a would be 72 miles/6 inches = x miles/ 1 inch. Cross multiply and you get 6x= 72, so x = 12 miles. Now you now that 1 inch equals 12 miles.
Part B tells you that Foston is 4 inches from Liberty, and asks you to figure out how far it is from West Quail. The WHOLE distance is 6 inches ( Liberty to West Quail) so the distance from Foston to West Quail is 6-4= 2 inches.
Remember 1 inch equals 12 miles, so 2 inches will equal 24 miles
I am not sure but I believe it is X
