why is critical value in a fixed duration analysis ill defined why is critical value ill defined what is meant by p-value in dna why does the critical value of the critical value vary between the two sets of data? why is critical data set important in a t-test why is critical value different between different scenarios why is the critical value in a t-test ill defined? why is critical value different between two different methods how do the p values of data compare why can p values differ between two scenarios why is p-value an ill defined term why the critical value for $t$-crit is different between the two conditions why the critical value for $p is ill-defined why does critical value vary between the two data sets when evaluating the validity of a p value, what determines which hypothesis is used to describe the significance of the resulting data? why does p value differ between two scenarios why would the critical value of p differ between the two conditions? why is critical value ill defined why is critical value different between two data sets which statement best describes the difference between the p value and the critical value?
