Answer : Chi-Squared test is a statistic that is being used by the researchers and data analysts to check the validity of a particular hypothesis. It is important in rejecting or accepting the hypothesis. Onchuri et. al. studied the applications of the Chi-Squared test and the areas in which it should not be used. The main focus of the study was to come up with a general idea to understand the loopholes and their remedies associated with the chi-squared test in a better way. In order to understand these loopholes, he reviewed the literature and also surveyed the effect of the statistic on the parameters such as the test of frequency, goodness of fit, homogeneity, independence, etc. He also proposed a general chi-squared model that can be used by scientists, researchers, and analysts all across the world to perform the data analysis without getting stuck in these loopholes.

1) In a study, the final statistical analysis showed that r square=0.35 (p<0.01). Which one of the following interpretations best explains this results? A) The model explains 65% of the variation in the outcome, because 1.00-0.35=65%. B) No conclusions can be drawn because it is not apparent whether the estimated coefficients for each covariate were statistically significant. C) About 35% of the variation in the outcome was explained by the independent variable(s). D) The model explains about 35% of the...

Find a research article that uses either: t-test, ANOVA, chi-square, or correlation. What was their hypothesis? What were their conclusions? What were the limitations of the analysis/analyses that they used? If you were to conduct a similar experiment, what would your hypothesis be? How would you go about collecting data (describe the nature of your sample: where would you access participants, how many people would you sample, etc.)? What analysis/analyses would you use to test your hypothesis? Why is this...

chi square goodness of fit test Epistasis is a phenomenon in which one gene controls the expression of another. In one case, a dihybrid cross should yield a 9:3:4 ratio.
