		inferential statistics.
		nonparametric statistics.
		parametric statistics.
		descriptive statistics. Which of these analytic techniques can be used to analyze dataacross three or more conditions of the IV? 1. t test 2. Analysis of variance 3. Chi-square 2 only 1 and 2 only 2 and 3 only 1, 2, and 3 In a chi-square test, we reject the null hypothesis when theobtained chi-square is lower than the critical tabled value. higher than the critical tabled value. close to the mean of the tabled distribution of chi-square. far from the mean of the tabled distribution of chi-square. Assume that you test the null hypothesis that there is nosignificant difference in the frequency with which students chooseamong the four alternatives when guessing the answer to a difficultquestion on a four-choice multiple-choice test. You select 24students at random and compare their answers. The number ofstudents choosing each answer is shown below: Answer: A B C D Number of Students Choosing: 3 9 2 10 Under the null hypothesis, what is the EXPECTED number of studentschoosing answer B? 4 6 9 24 The purpose of a chi-square goodness-of-fit test is to determinewhether sample frequencies are proportional to populationfrequencies. sample frequencies are the same as population frequencies. sample frequencies between two different samples aresimilar. sample frequencies are randomly distributed
