A characteristic or measure obtained by using the data values from a sample.
What is Statistic
100
Value that occurs most often in a data set.
What is Mode
100
Mean is left of the median, and mode is to the right.
What is Negatively Skewed Distribution.
100
The highest value minus the lowest value.
What is Range
200
The standard deviation divided by the mean.
What is Coefficient of Variation
200
Halfway point in a data set.
What is Median
200
Majority of data values fall to the left of the mean and cluster at the lower end of the distribution.
What is Positively Skewed Distribution
200
Square root of the variance.
What is Standard Deviation
300
They tell where a specific data value falls within the data set or its relative position in comparison with other data values.
What is Measures of Position
300
Found by adding the values of the data and dividing by the total number of values.
What is Mean
300
When majority of data values fall to the right of the mean and cluster at the upper end of distribution.
What is Negatively Skewed Distribution
300
Average of the squares of the distance each value is from the mean.
What is Variance
400
Obtained by subtracting the mean from the value and dividing the result by the standard deviation.
What is Standard Score / Z Score
400
Sum of the lowest and highest values in the data set divided by 2.
What is Midrange.
400
When the mean is to the right or the median, and the mode is to the left.
What is Positively Skewed Distribution
400
This rule states that approximately 68% of data values will fall within one standard deviation of the mean.
Approximately 95% of the data values fall within two standard deviations of the mean.
Approximately 99.7% of data values will fall within three standard deviations of the mean.
What is Empirical Rule
500
A statistic whose value approximates the expected value of a population variance.
What is Unbiased Estimator
500
Rough estimate of the middle.
What is Midrange
500
Data values are evenly distributed on both sides of the mean.
