For the following scores, find the (a) mean, (b) median, (c) sum of square variances, (d) variance, and ( e ) wag devation: 2, 2, 0, 5, 1, 4, 1, 3, 0, 0, 1, 4, 4, 0, 1, 4, 3, 4, 2, 1, 0 a) Mean = (2+2+0+..+1+0)/21 = 42/21= 2 Mean = 2 b) coherent selective information is: 0,0,0,0,0,1,1,1,1,1,2,2,2,3,3,4,4,4,4,4,5 average = 2 c) Sum of squared deviations =SS= (2-2)2+(2-2)2+..+ (0-2)2 =20+5+2+20+9=56 SS= 56 d) Variance = SS/N= 56/21=8/3 Variance = 8/3 e) Standard deviation = SD = 1.633 SD = 1.633 In a study by Gonzaga et al. (2001), romantic couples answered questions almost how more than they heat their partner and also were videotaped while revealing something about themselves to their partner. The videotapes were by and by rater by trained judges for dis sympathetic signs of affiliation. Explain to a person who has never had a signifier in statistics the results for self-report whop for the partner and for the routine of seconds leaning toward the partn er. Self-reported love for the partner on average is good (around 5 on a cale from 0 to 8) of men and womed these numners are similar (5.02 and 5.11) sd for two groups is similar too The number of seconds leaning to the partner on average is about 32 (32.27 for men and 31.

36 for women) and the sd is similar too For the following scores, find the (a) mean, (b) median, (c) sum of squared deviations, (d) varaince, and (e) stock deviation 1,112; 1,245; 1,361; 1,372; 1,472 a) Mean = (1,112+1,245+..+1,472)/5 = 1,312.4 Mean = 1,312.4 b) Ordered data is: 1,112; 1,245; 1,361; 1,372; 1,472 Median = 1,361 c) Sum of squared deviations =SS= (1,112-1,312.4)2+..+ (1,472-1,312.4)2 =76 ,089.2 SS= 76,089.2 d) Variance = SS/N= 76! ,089.2/5=15,217.84 Variance = 15,217.84 e) Standard deviation = SD = SD = 123.36 On a threadbare measure of hearing ability, the mean is 300 and the standard deviation is 20. Give the Z scores for persons who score (a) 340, (b) 310, and (c) 260. a) z-score = (340-300)/20 = 2 b)...If you ask to get a full essay, order it on our website: OrderEssay.net
