Best ResponseYou've already chosen the best response.0for set 1: 17 and Set 2: 18

Best ResponseYou've already chosen the best response.0Because you divide 18 by 17

Best ResponseYou've already chosen the best response.0MAD  Mean absolute deviation of a component of a data set is the total difference between that component and a given point. In general, the central tendency is the measure of a point from which the deviation is measured, more frequently the median or sometimes the mean of the data set. The Mean Absolute Deviation also called as average deviation of a data set {x1, x2, ..., xn} is the average of the absolute deviations and is a abstract statistic of statistical distribution or set of data. The mean absolute deviation often abbreviated as MAD and calculated from the formula

Best ResponseYou've already chosen the best response.1Ok, so your MAD are correct

Best ResponseYou've already chosen the best response.1now we subtract the first data set mean from the second data set mean

Best ResponseYou've already chosen the best response.0Ok back @YoungStudier

YoungStudier

Best ResponseYou've already chosen the best response.1ok, so now we divide that by the larger MAD

YoungStudier

Best ResponseYou've already chosen the best response.1Remember: If the ratio is less than or equal to one, the two distributions are similar. What do you think the answer is now?

Best ResponseYou've already chosen the best response.1And the question with 0.4, I was wrong, that is actually 0.4 (positive) because of the absolute value lines around the meanmean/MAD larger

What can she infer about the weights of Breed 1 dogs and Breed 2 dogs? Breed 1: {45, 38, 49, 52, 51} Breed 2: {36, 35, 44, 50, 40} A. Breed 1 dogs and Breed 2 dogs have similar weight distributions. B. Breed 1 dogs and Breed 2 dogs have somewhat similar weight distributions. C. Breed 1 dogs and Breed 2 dogs have no overlap in their weight distributions. D. Breed 1 dogs and Breed 2 dogs have identical weight distributions.
