Several statistical methods were performed with the three types of experimental errors in mind these methods are the q-test, standard deviation and to determine whether a candidate is an outlier or not, q-test was used figure 11 gaussian curve xq − xn qexp = (1) the gaussian curve for data. It is an important concept since it is a precise indicator of the degree of variability within a set of numbers smaller standard deviation denotes closer data the narrower the confidence interval, the more precise the results are q-test is a statistical test used to determine whether a suspected value. 4 statistical analysis from set 2 is more accurate due to having more trials, making the margin for deviation smaller 5 to determine the closeness or conciseness between data sets gravimetric determination of phosphorus in fertilizer samples.

Coefficient of determination, in statistics, r2 (or r2), a measure that assesses the ability of a model to predict or explain an outcome in the linear regression setting more specifically, r2 indicates the proportion of the variance in the dependent variable (y) that is predicted or explained by linear. In statistics, the coefficient of determination, denoted r2 or r2 and pronounced r squared, is the proportion of the variance in the dependent variable that is predictable from the independent.
