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.
What do you mean by data integrity?
Data integrity is a term used in databases. In its broadest use, "data integrity" refers to the accuracy and consistency of data stored in a database, data warehouse, data mart or other construct. The term - Data Integrity - can be used to describe a state, a process or a function - and is often used as a proxy for "data quality".
What are the numbers used to describe the center of a set of data?
data pattern
How would you describe a variance?
A variance is a statistical measure that quantifies the spread or dispersion of data points in a dataset. It indicates how much each data point differs from the mean of the dataset. A higher variance value suggests a wider spread of data points, while a lower variance value indicates a more clustered data distribution.

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
Why standard deviation is more often used than variance?
Both variance and standard deviation are measures of dispersion or variability in a set of data. They both measure how far the observations are scattered away from the mean (or average). While computing the variance, you compute the deviation of each observation from the mean, square it and sum all of the squared deviations. This somewhat exaggerates the true picure because the numbers become large when you square them. So, we take the square root of the variance (to compensate for the excess) and this is known as the standard deviation. This is why the standard deviation is more often used than variance but the standard deviation is just the square root of the variance.
Can the median be used to describe both categorical data and numerical data?
Can the median and mode be used to describe both categorical data and numerical data
