A Goodness of Fit Test is a statistical test used to determine how well an observed sample data fits an expected theoretical distribution. It assesses whether any differences between observed and expected frequencies are statistically significant or simply due to random chance.
congrats on reading the definition of Goodness of Fit Test. now let's actually learn it.
Expected Frequencies: These are calculated frequencies based on theoretical distributions and serve as a basis for comparison in a Goodness of Fit Test.
Observed Frequencies: These are the actual frequencies obtained from sample data that are compared to expected frequencies in a Goodness of Fit Test.
Null Hypothesis: In statistical hypothesis testing, the null hypothesis states that any observed differences between observed and expected frequencies are due to random chance and not significant.
