Statistics
Once data is loaded into your project, statistics for your raw data set can be displayed by clicking on the Statistics button on the tool bar.
Calculated Statistics
-
Minimum: Numerically the smallest value of the field.
-
Maximum: Numerically the largest value of the field.
-
Average: The time-weighted average of the field. This is calculated as a function of the time spent at each specific value, divided by the total time period.
-
Variance: The time-weighted variance of the field. A measure of statistical dispersion, averaging the squared distance of its possible values from the expected value, which is the mean value.
-
Std Dev: The time-weighted standard deviation of the field - a measure of dispersion of the field values.
-
Skew: The time-weighted skew of the field. The measure of the asymmetry of the distribution values of the fields. A distribution has a positive skew (right-skewed) if the right (higher value) tail is longer or fatter and negative skew (left-skewed) if the left (lower value) tail is longer or fatter.
-
Kurtosis: The time-weighted kurtosis of the field. A measure of whether the data distribution is peaked or flat, relative to a normal bell curve distribution.
CSense calculates Excess Kurtosis where the kurtosis of 0 is commonly interpreted as a normal distribution.
A positive excess kurtosis (excess kurtosis greater than 0) has a more acute peak (a higher probability than a normally distributed variable of values near the mean) and fat tails (that is, a higher probability than a normally distributed variable of extreme values).
A negative excess kurtosis (excess kurtosis lesser than 0) has a smaller peak (a lower probability than a normally distributed variable of values near the mean) and thin tails (a lower probability than a normally distributed variable of extreme values).

-
This option calculates the statistics for the original data excluding lag and limit information

-
Cleaned data
-
This option calculates the statistics for the data set including lag and limit information - once limits and lags have been entered/calculated the data is referred to as having been cleaned.

This option calculates the statistics for the original data (brushed and non-brushed data)

-
Brushed data
-
This option calculates the statistics for only the brushed data

-
Non-brushed data
-
This option calculates the statistics for only the non-brushed data
Export Option
This option exports the statistics view as a Comma Separated Value (CSV) file.
