You intend to conduct a test of homogeneity for a contingency table with 3 categories in the column variable and 6 categories in the row variable. You collect data from 339 subjects. What are the degrees of freedom for the x distribution for this test? d.f. =

Consider the data that was obtained from a random sample of 41 credit card accounts. Identify all the averages (mean, median, or mode) that can be used to summarize the name of credit card (e.g., MasterCard, Visa, American Express, etc.) O median if it exists mean and mode if it exists O mean, median, and mode if it exists O mode if it exists mean if it exists

The mean sales prices for a sample of homes in a city was $250,000. The median sales price of these same homes was $459,000 . The distribution of home sale prices in this city is: Right Skewed Cannot tell from mean and median alone. Symmetric Left Skewed

8 students took a test. 3 of them scored 4, 4 and 7 marks respectively. Given that the median and mode is 5, the upper quartile is 8 and the largest score is thrice the smallest score, find the scores of the other 5 students.

thanks for attempting my question. would appreciate a quick response and an explanation. thanks Question 1 of 4 Assume that we have 6 manifest variables and 3 factors. The communality of 3 on variable 74 is obtained with the following: 34 O B. Y 34 O D. Y43 Question 3 of 4 Assume we have 6 manifest variables and 3 factors. The proportion of variance in the 2nd manifest variable accounted for by all of the factors can be represented as follows: O A. 22 О в. C. 13 33 Y 63 O D. 2-2; = Y21 +?22+?23

To study how well rats can learn, behavioral scientists used a sample of rats in a maze experiment. Each rat had to find itway through a maze to reach a treat at the end. The rat was timed on its first trial run and again on its tenth eighth trial run. The difference in the times was recorded for each rat.   Which of the following is the most appropriate procedure for the scientists to use?   A- A matched pair t-interval for a mean diffderence B- A two sample t interval for a difference between means C- a one sample t interval for a sample difference  D-A one sample z interval for a population proportion E- A two sample z interval for a difference between proportions

How many sources of between-group variation are measured in a two-way between-subjects ANOVA? Group of answer choices a. 4 b. 2 c. 3 d. 5

An analysis of variance produces SSbetween = 75 and MSbetween = 15. In this analysis, how many treatment conditions are being compared?​ Select one: a. ​ 3 b. ​ 4 c. ​ 5 d. ​ 6

Which of the measures of central tendency do you think you would use the most? Provide one (1) example. Explain what is meant by positive bias and negative bias in relation to the mean, mode, and median. If you were given a choice between the mean, median, or mode to calculate measures to make a decision about a set of data, which of the three measures would you use, and why?
