Descriptive Statistics Tools

Dates Collected The number of dates collected.
Number of points collected Number of values collected.
Mode The mode is the most frequently occurring value.
Mean The sum of the values divided by the total amount of numbers.
Median The median is the number in the middle of a dataset.
Max Value Largest value in data set.
Min Value Smallest Value in data set.
Skewness Characterizes the degree of asymmetry of a distribution around its mean.
Kurtosis Relative peakedness or flatness of a distribution.
Range Difference between largest and smallest number.
90 percentile Number where 90% of the values fall below.
80 Percentile Number where 80% of the values fall below.
70 Percentile Number where 70% of the values fall below.
60 Percentile Number where 60% of the values fall below.
50 Percentile Number where 50% of the values fall below.
40 Percentile Number where 40% of the values fall below.
30 Percentile Number where 30% of the values fall below.
20 Percentile Number where 20% of the values fall below.
Standard Error This is the standard deviation divided by the square root of the sample size.
Standard Deviation Shows the variation from the mean.
99% Confidence Interval From the data collected there is a 99% chance the true mean lies between the numbers.
95% confidence Interval From the data collected there is a 95% chance the true mean lies between the numbers.
90% Confidence Interval From the data collected there is a 90% chance the true mean lies between the numbers.
# of Detects List the number of non-detects values.
# of Non Detects Counts the number of non-detects.
Detection Limit minimum Lowest detection limit.
Detection Limit maximum Highest detection limit.
