Better than my new dishwasher and microwave combined. I have been using NCSS in my high school class room for 22 years. I find it very easy to use and my students use it to calculate their results for their lab reports, science fair projects, and now they are using it for AP Research projects.

It can be used for everything from the basics to the most advanced statistics. NCSS is very affordable for any high school budget. He has more than 23 years of experience in teaching and research. He has developed several web based and MOOC courses in NPTELincluding on regression analysis and has conducted several workshops on statistics for teachers, researchers and practitioners.

He has received several national and international awards and fellowships. He has authored more than 75 research papers in national and international journals. He has written four books and one of the book on linear models is co- authored with Prof. His research areas of interest are nonparametric regression, and shape restricted regression.

He has recently completed his Ph. Course certificate The course is free to enroll and learn from. But if you want a certificate, you have to register and write the proctored exam conducted by us in person at any of the designated exam centres.

It returns a reference to a hash where the keys are the numerical values of the partitions used. The minimum value of the data set is not a key and the maximum value of the data set is always a key.

The number of entries for a particular partition key are the number of items which are greater than the previous partition key and less then or equal to the current partition key. As an example,. This allows for non-uniform distributions as well as trimmed or sample distributions to be found. Note that unless the set of bins contains the full range of the data, the total counts returned will be less than the sample size. Kept for compatibility reasons with previous versions of Statistics::Descriptive and using it is discouraged.

The array that is returned can be "coerced" into a hash structure by doing the following:.
