What is the 'mean' in statistics? It is the average of a set of numbers, calculated by summing the values and
dividing by the count of numbers.
What is the 'median' in a dataset? It is the middle value in a sorted list of numbers, separating the higher half from
the lower half.
How is the 'mode' of a dataset determined? It is the value that appears most frequently in a data set.
What does the 'range' of a dataset measure? It measures the difference between the highest and lowest values in the dataset.
In statistics, what does 'variance' measure? It measures how far a set of numbers is spread out from their average value (the
mean).
What is the 'standard deviation' and what is its relationship It is a measure of the amount of variation or dispersion of a set of values, and it is
to variance? the square root of variance.
What does 'covariance' indicate in statistics? It indicates the joint variability of two random variables, showing how they change
together.
What is another name for the Normal distribution? The Gaussian distribution.
The 68-95-99.7 rule in a Normal distribution states that One
approximately 68% of the data falls within _____ standard
deviation(s) of the mean.
According to the 68-95-99.7 rule, what percentage of Approximately 95%.
data falls within two standard deviations of the mean in a
Normal distribution?
What is the 'expected value' of a random variable? The long-run average value of repetitions of the experiment it represents.
