Chi Square/Hardy-Weinberg Flashcards
What is a null hypothesis?
A hypothesis that states the variable will have no effect. Any difference between the expected and observed data is due entirely to chance.
What is the “expected” data?
Data that proves that the variable had no effect.
What is the “observed” data?
The actual data collected from the experiment
What determines if you accept or reject the null hypothesis?
If the value is greater than the threshold for the given degrees of freedom
What are degrees of freedom?
The number of classes or categories minus one
How does chi-square value relate to probability?
The lower the chi square value, the greater probability that the difference between the observed and expected results are due to chance.
