# Available Metrics Types

 Data Type Description Nulls All Types The count of rows with a null value in the column e.g. Sample dataset: Null Null 23 Metric value: 2 Count All Types The total number of rows in a table e.g. Sample dataset: 78 6 89 23 45 Metric value: 5 Cardinality All Types The count of distinct elements in the column. This metric should be used when you expect a fixed number of value options e.g. Sample dataset: Cat Dog Cat Metric value: 2 Duplicate All Types The count of rows with a duplicate value in the column (excluding the unique value). eg Sample dataset: Apple Apple Pear Pear Banana Pear Metric value: 3 Apple has 1 duplicate, Pear has 2 duplicates, result is 3 Min Numeric The minimum value of the column e.g. Sample dataset: 78 6 89 23 45 Metric value: 6 Max Numeric The maximum value of the column e.g. Sample dataset: 78 6 89 23 45 Metric value: 89 Median Numeric The median of the column. The median is computed as the 50th percentile, and will only return a value that is in the dataset e.g. Sample dataset: 78 6 89 23 45 Metric value: 45 Skewness Numeric The statistical skew of the column. The skew is used to determine how evenly the values are distributed about the mean e.g. Sample dataset: 78 6 89 23 45 Metric value: 0.0303028253 Variance Sample Numeric The variance of a column from its sample mean. This should be used to calculate the variance when the data represents a sample taken from a larger data set e.g. Sample dataset: 78 6 89 23 45 Metric value: 1244.7 Variance Population Numeric The variance of a column from its population mean. This should be used to calculate the variance when the data represents the entire data set e.g. Sample dataset: 78 6 89 23 45 Metric value: 995.76 Geometric Mean Numeric The geometric mean of a column e.g. Sample dataset: 78 6 89 23 45 Metric value: 33.644590126644 Freshness (hrs) Date Timestamp The difference in hours of the maximum value of the column and the metric’s collection time e.g. Sample dataset in UTC (Metric collected at 2022-12-07 03:48:00 UTC): 2022-12-06 05:24:26 2022-12-07 01:33:362022-12-07 00:33:44 Metric Value: 2.07333
