When testing the independence of variables from a two-way table of observed data, you have to use the:
a. Standard normal table b. T-table
c. Chi-square table
d. Linear regression
e. None of these
Homework Answers
Option C
Chi square table
While testing for independence in two way table we have to compare the calculated test statistic with the table value of chi square distribution with (n-1)*(m-1) degrees of freedom where n is number of columns and m is number of rows.
The test statistic follows the chi square distribution and hence chi square tables are required.
Do comment if you have any doubt.
Thank you !!

Suppose you have a sack of mixed potatoes, with 14 red, 10 all-blue, 7 Yukon Gold, and 20 Russett. You suspect that the farmer is selling the different varieties at different rates. You think that when she fills sacks of potatoes, she puts in lots of Russetts and not very many all-blues. What test do you use to determine if that's true or not? O Chi-square goodness of fit test (one-way chi- square) O Chi-square test of independence (two-way chi-square)...

For the following experiment/question, pick the most appropriate statistical test. You have the following statistical tests as choices: some may be used more than once, others not at all. Assume homogeneity of variance (where applicable) and the validity of parametric tests (where applicable), unless something is directly stated (e.g., “the data are not at all normal”) or otherwise indicated (viz., by the inspection of the data) which would indicate a strong and obvious violation of an assumption. This means you must...

You are given the following regression results, where the sample size is 10., Coefficients Standard Error Intercept -1.2 1 X 2 2 a) What is the value of the t test statistic? b) At the α = 0.05 level of significance, what are the critical values? c) Based on your answer to (a) and (b), what statistical decision should you make?

(1 point) Recall in the course we learnt how to display data of two categorical variables by means of a contingency table. In this question, we will formulate a measure to quantify the level of association between the two categorical variables. Such a measure is often used in a statistical test called Chi-square test for assessing whether there is an association between two categorical variables. This question is also used to motivate the learning of independence and to connect the...
