Question

The following table displays the calculations required for the chi-squared analyses O E O-E (O-E) (O-E)?/E 16-20 yr. old who prefer 13.85 -3.85 14.82 1.07 dogsledding 16-20 yr. old who prefer snow 30.77 -3.77 14.21 | .46 shoeing 16-20 yr. old who prefer 29.23 33.77 1140.41 39.05 snowboarding 21-25 yr old who prefer 13.15 3.85 14.82 1.13 dogsledding 21-25 yr old who prefer snow 29.23 3.77 14.21 .48 shoeing 21-25 yr. old who prefer 52.61 -7.61 57.97 1.10 snowboarding 1. What is the critical value for this chi-square analysis? 2. Using the completed table determine the final chi-squared, write the results as you would in a research article and interpret thesis results. Include an interpretation of what the findings mean and use the above table to determine where any differences are found.

Answer 1

matrix is 2x3 a . f = (-1) ( -1) =(2-1)(3-1) 2 - ritical value =15.991 text statistic = r = Z roii-eij eir je = [co-E = 43.2g We reject the nwl hypo. conclude that. Age and prefrence are dependent on each other.
