    The name given to goodness of fit test was derived based on the hypothesis tested and how good the observed frequencies fit a given pattern. To make a goodness of fitness test, the sample size should be large enough so that the expected frequency for each category is at least 5. There are four commonly used goodness of fit tests: The Chi-Square, Kolmogorov-Smirnov, Anderson-Darling, and Shipiro-Wilk. Observed frequencies, denoted by O, are counts made from experimental data - whereby you...

    4. In an experiment there were Nexp values measured. The expected values based on similar measurements are known. Both sets are presented in the Table of data. The question that arose was whether the differences between the observed and expected data are due to chance. Use the chi-square test to determine the probability that the differences arose from chance. Data Index Observed Expected 1 8.00 6.40 2 10.00 13.60 3 16.00 13.00 4 7.00 9.00 5 13.00 10.00 6 11.00...

    Punnett Square 4 describes a cross between two heterozygous parents (PpSs x PpSs). Was this Punnett square a good predictor of offspring phenotypes? Use the results of the chi-square test to support your answer. Chi-square results below: Degrees of Freedom= 3 P-value range= Between 0.500 and 0.050. (p>0.05) Conclusion= There is no significant statistical difference between the observed and expected values.

    Please help me answer #3. The chi^2 value means nothing on its own-it is used to find the probability that, assuming the hypothesis is true, the observed data set could have resulted from random fluctuations. A low probability suggests that the observed data are not consistent with the hypothesis, and thus the hypothesis should be rejected. A standard cutoff point used by biologists is a probability of 0.05 (5%). If the probability corresponding to the chi^2 value is 0.05 or...
