![]() ![]() Reject or Fail to Reject the Null Hypothesis? The closer the p-value is to zero, the stronger the evidence is in support of the alternative hypothesis, H a H_a H a . The p-value can be used in the final stage of the test to make this determination.īecause it is a probability, the p-value can be expressed as a decimal or a percentage ranging from 0 to 1 or 0% to 100%. The goal of a hypothesis test is to use statistical evidence from a sample or multiple samples to determine which of the hypotheses is more likely to be true. In a hypothesis test, you have two competing hypotheses: a null (or starting) hypothesis, H 0 H_0 H 0 and an alternative hypothesis, H a H_a H a . It represents the probability of observing sample data that is at least as extreme as the observed sample data, assuming that the null hypothesis is true. You can read more about what's coming at How do I create an assessment using Quizzes.Calculating p-Values for Discrete Random VariablesĬalculating p-Values for Continuous Random VariablesĪ p-value (short for probability value) is a probability used in hypothesis testing. The good news is that in the new quiz tool, Quizzes.Next, it will be possible to apply a point value to the quiz without having to adjust the points for the individual questions, and you will also be able to display the grade as a percentage. To save some time, you could edit the quizzes by dragging all of the questions into a single question group and applying a point value per question that would add up to 100, keeping in mind that this will also have the effect of randomizing the question order ( How do I create a quiz with a question group to randomize quiz questions? ) And it even had a third advantage, in that it made me evaluate each question individually and decide which ones should contribute more to the total, and which ones less, depending on where the questions fell in the Bloom's Taxonomy hierarchy. This had a two-fold benefit: it allowed me to make all the quizzes of equal value, and I could mimic a percentage in the Gradebook (since quizzes don't display as percentages, only as points). So, when I built my quizzes in Canvas, I manipulated the point values of the individual questions to make them add up to 100. Total points possible for a Canvas quiz stems from the total value of the points for the quiz questions in other words, it's not currently possible to apply an overall, or top-down, point value to a quiz. ![]() This is something I had to plan for when I first started building my courses, so I thought I'd chime in to share my experience. Hi, ericwerth has given you great advice. ![]()
