In this article we will discuss about the definition of âtâ Test with example. t-Test is a method to find out whether the difference is quite significant to conclude that the two samples are really different, or the difference in two samples is simply because of some fluctuation, or due to some error or lapses in the experiment. In some [...]
In this article we will discuss about the definition of standard deviation with example. Also learn about standard error. The standard deviation or mean error is an absolute measure of dispersion of an individual series or a frequency distribution, is the square root of the arithmetic mean of the squares of deviations of values from their arithmetic mean. This measure [...]
This article provides a study note on analysis of variance. It is a measure of variation among treatments/genotypes/replications, etc., and is obtained by dividing the sum of squares (SS) by corresponding degrees of freedom (n â 1) to get mean sum of squares (MSS), i.e., variance. Variance parameter widely used in statistical analysis is the comparison among different sample means. [...]
