Array Statistics Detail
If you have added a slice, these statistics describe only the information currently being displayed; they do not describe the entire array. For example, if an array includes positive values, but a slice omits array values that are more than 0, the median value is negative even though the entire array’s real median value is more than 0.
Count
The total number of displayed array values. If you’re displaying a floating-point array, this number doesn’t include NaN or Infinity values.
Zero Count
The number of elements whose value is 0.
Sum
The sum of all the displayed array’s values.
Minimum
The smallest array value.
Maximum
The largest array value.
Median
The middle value. Half of the array’s values are less than the median, and half are greater than the median.
Mean
The average value of array elements.
Standard Deviation
The standard deviation for the array’s values.
Quartiles, First and Third
Either the 25th or 75th percentile values. The first quartile value means that 25% of the array’s values are less than this value and 75% are greater than this value. In contrast, the third quartile value means that 75% of the array’s values are less than this value and 25% are greater.
