p estadística 15
The p-value or value of probability, is a statistical measure that helps scientists determine if their assumptions are correct or not. P-values are used to determine if the results of the experiments are within the normal range of values for the observed events. As a general rule, if the p of a set of data value is below a certain amount (such as 0.05), scientists reject the quot; quot null hypothesis; of their experiment. The values p are currently in a reference table to first calculate the value of the quot; Chi-square-quot; which measures the difference between the expected values and the observed in an experiment...
