1. For the following scores, find the mean, median, and the mode. Which would be the most appropriate measure for this data set?

2, 2, 0, 5,1, 4,1, 3, 0, 0, 1, 4, 4, 0,1, 4, 3, 4, 2, 1 Mean- (2+2+0+5+1+4+1+3+0+0+1+4+4+0+1+4+3+4+2+1)/20= 2.15 Median- 2.10 Mode- numbers 1 and 4 The most appropriate measure for this data set would be mean as it involves all the numbers combined.

2. Based on the scale of measurement for each variable listed below, which measure of central tendency is most appropriate for describing the data?

a. The time (in years) it takes a sample of students to graduate college

b. The blood type (e.g., Type A, B, AB, O) of a group of participants

c. The rankings of college undergraduate academic programs

Chapter 4

3. An expert reviews a sample of 10 scientific articles (n = 10) and records the following numbers of error in each article: 0, 4, 2, 8, 2, 3, 1, 0, 5, and 7. Compute the SS, the variance, and the standard deviation for this sample using the definitional and computational formulas.

4. A psychologist interested in political behavior measured the square footage of the desks in the official office for four U.S. governors and of four chief executive officers (CEOs) of major U.S. corporations. The figures for the governors were 44, 36, 52, and 40 square feet. The figures for the CEOs were 32, 60, 48, 36 square feet.

Two boats, the Prada (Italy) and the Oracle (USA), are competing for a spot in the upcoming America’s Cup race. They race over a part of the course several times. The sample times in minutes for the Prada were: 12.9, 12.5, 11.0, 13.3, 11.2, 11.4, 11.6, 12.3, 14.2, and 11.3.

Explain and give an example for each of the following types of variables: a. Nominal: Measurement where a number is assigned to represent something or someone else. An example of nominal could be credit card numbers, social security numbers, or zip codes. b. Ordinal: Measurement that shows the order or rank of items. An example of ordinal could be ranking places in a contest, or test scores. c. Interval: Measurements that do not have a true zero and are composed of equal units. An example of interval could be temperature as temperature has no true zero. d. Ratio scale: Measurement that has a true zero and is distributed equally. An example of ratio could be weight height, time, or age. e. Continuous: Measured as a long continuum at any place beyond the decimal point and can be measured in fractional units. An example of this would be Olympic athletes as judges will time them to the nearest millionth place. f. Discrete: Measurement in which measurements are in whole units. An example of this could be used when a census of the population is taken. g. Quantitative: Varies by amount, is measured numerically and usually collected by counting or measuring. An example of this could be measuring food intake by......

According to Sternberg, what is Kara’s IQ? Conduct research and interpret her score. Choose two theories of intelligence. Write a 150- to 200-word discussion on the components of each theory, and how they differ in relation to Spearman’s g factor. According to Sternberg, Kara’s IQ is 90 because at ages 10,11,12,13 the level of IQ is more than ages above 17 because of initiation to adulthood. Kara’s scores will be high because children with elevated levels of intelligence are more likely to learn in the school setting comparatively to their peers with lower scores. This gives evidence to the relationship between IQ scores and school performance. The triarchic theory of intelligence was created by Sternberg while he was piloting research on human intelligence. The triarchic theory is made up of three components. The first component addresses the relationship between intelligence and......
