Document Summary

This brings us to the topic of the indicator function which is simply the value 1 if the value of x is a value that is permitted in the range of the experiment and 0 otherwise. So in this case, i can represent p(x) as 1/36 * i(x) One thing to note is that the value of the probability will be greater than 0, if the value of x is within the range of the function and 0 otherwise. And as is the general case, the sum of the probabilities of all the x values would equal to 1. What this means is that for every value of the variable that has a probability greater than 0, the graph will jump up from its previous value.

The "p" in p-value stands for probability. More specifically, it is the probability of making a mistake. The p-value is a number that is generated by the computer based on the data the researcher has inputted. The p-value is a number that can range anywhere from 0 to 1. After the p-value is calculated by the computer it is compared to alpha or the level of significance which, in the social sciences, is generally set to 0.05. If I ran an experiment and myp-value was calculated to be 0.06 what would that mean?
