2. The spinner at the right is spun 12 times. It lands on blue 1 time,
a. What is the experimental probability of the spinner landing on blue?
b. Compare the experimental and theoretical probabilities of the spinner
landing on blue. If the probabilities are not close, explain a possible
reason for the discrepancy

1. why is a frequency distribution useful? it allows researchers to see the "shape" of the data. it tells researchers how often the mean occurs in a set of data. it can visually identify the mean. it ignores outliers. 2. the is defined by its mean and standard deviation alone. normal distribution frequency distribution median distribution marginal distribution 3. approximately % of the data in a given sample falls within three standard deviations of the mean if it is normally distributed. 95 68 34 99 4. a data set is said to be if the mean of the data is greater than the median of the data. normally distributed frequency distributed right-skewed left-skewed
