A measure used to describe the variability of data distribution is what?
A measure used to describe the variability of data distribution is the standard deviation. It quantifies the amount of dispersion or spread in a set of values, indicating how much individual data points differ from the mean. A higher standard deviation signifies greater variability, while a lower standard deviation indicates that the data points are closer to the mean. Other measures of variability include variance and range.
What SPSS procedures can be used for data screening of categorical variables?
variance
Besides the term bell curve what other descriptive term can be used for showing how a data set as a whole is spread around the mean?
Variance
What describes the spread of data?
Range, variance, and standard deviation usually are used to describes the spread of data.
Is sigma square equal to variance?
Yes, sigma squared (σ²) represents the variance of a population in statistics. Variance measures the dispersion of a set of values around their mean, and it is calculated as the average of the squared differences from the mean. In summary, σ² is simply the symbol used to denote variance in statistical formulas.
How would you describe a variance?
A commonly used method is to determine the difference between what was allowed by standard costs, which are the budget allowances, and what was actually spent for the output achieved. This difference is called a variance.

What is the total deviation formula used to calculate the overall variance in a dataset?
The total deviation formula used to calculate the overall variance in a dataset is the sum of the squared differences between each data point and the mean of the dataset, divided by the total number of data points.
What is the Formula for Vars?
The formula for calculating variance (Var) is the average of the squared differences between each data point and the mean of the data set. It is used to measure the dispersion or spread of a set of data points around the mean.
What is the term used to describe the spread of values of a variable?
The term used to describe the spread of values of a variable is "dispersion." Dispersion indicates how much the values in a dataset differ from the average or mean value. Common measures of dispersion include range, variance, and standard deviation, which provide insights into the variability and distribution of the data.

What term is used to refer to the data that are used to describe the data in a database?
Data definition is the term used to describe expected data value.
What measures are used to describe variability?
Generally, the standard deviation (represented by sigma, an O with a line at the top) would be used to measure variability. The standard deviation represents the average distance of data from the mean. Another measure is variance, which is the standard deviation squared. Lastly, you might use the interquartile range, which is often the range of the middle 50% of the data.
What is a single number used to describe a set of data mean median mode?
2,5,4,5
