Standard deviation: standard deviation is a measure of dispersion of a population or a data set from the observed mean. A low value indicates data has very close value to the meanwhile large values indicate highly deviated or spread data. In this test Standard deviations of initial blood pressure were 9.02 and 10.62 in placebo and calcium groups respectively.Variance is a measure of average statistical dispersion. Like standard deviation it also gives an idea about the distance of its possible values from the expected value of the mean. Whereas the mean is a way to describe the location of a distribution, the variance is a way to capture its scale or degree of being spread out.Hypothesis test: hypothesis test is a statistical method of identifying the difference between two populations or samples. This helps to find out these populations are different or equal. Here independent sample T-Test was performed as the hypothesis test.Level of significance: the significance level of a test is a probability of a null hypothesis to be true. As an example in above test level of significance for final blood pressure between placebo and treatment groups is 0.36. This means null hypothesis (i.e. treatment has no effect) has 0.36 or 36% probability to exit. Usual cutoff for significance level is 0.05 or 5% and the null hypothesis is rejected if the Level of significance is below 0.05.The standard error of the sample means: is the standard deviation of the error in the sample mean relative to the actual mean.
