Standard Deviation
of a statistical data is defined as the positive square root of the arithmetic mean of the squared deviations of items from their arithmetic mean of the series under consideration. The standard deviation is denoted by s (sigma). The standar..

Merits: - Mean deviation is easy to calculate. This measure is simple to understand. This can be calculated from any average. Its value is based upon all the (observations) items of the data. It is less affected by extreme observations. It gives us an idea about how the items ar..

where l is a finite number and is equal to np. The sum of the probabilities P(X = r) or simply P(r) for r = 0, 1, 2, is 1. This can be seen by putting r = 0, 1, 2, in (4) and adding all the probabilities. Also, each of the probabilities is a non-neg..

This Tutor Vista is GREAT! loved this session, it helped me heaps.
Tutor Vista tutor helped me understand and gave me some practices and showed me how to do them.
Terific helped showed how to apply formulas i will study these examples to go further--much gratitude--will come back again ThankYou
This tutoring impressed me a lot! not only did the tutors helped me with currect lessions i needed help with, but they prepared me for future trig lessons to come and very useful imformation - gabriella
