Question 1

As compared to a Z score, a raw score is:

Accepted Answer

A raw score is an ordinary score that represents the actual score that a person obtains on a test or assessment without any transformation or standardization. A Z score, on the other hand, is a standardized score that represents the distance of a raw score from the mean in units of standard deviation. Therefore, a raw score is not a transformed, scaled, or standardized score, but instead represents the original, unprocessed score obtained by a person on a test or assessment.

Question 2

A researcher studying the sociological implications of cultural diversity conducts lengthy interviews with members of various cultural communities. What kind of method is this sociologist probably using?

Accepted Answer

The sociologist is likely using qualitative techniques, specifically conducting lengthy interviews with members of various cultural communities. Qualitative research methods rely on collecting data through observation, interviews, and other non-quantitative methods in order to gain a deep understanding of a particular phenomenon. In this case, the researcher is likely using interviews to gather rich, descriptive data about the experiences of individuals from different cultural backgrounds.

Question 3

For the questions below: A statistics student (Lee)wants to compare his final exam score to his friend Zoey's final exam score from last year. However, the two exams were scored on different scales. Lee asks Zoey for the mean and standard deviation of her class on the exam as well as her final exam score. Compute the Z scores for Lee and Zoey. Lee: Final exam score = 85; Class: M = 70; SD = 10
Zoey: Final exam score = 45; Class: M = 35; SD = 5

Accepted Answer

Lee's Z score = (85 - 70) / 10 = 1.5; Zoey's Z score = (45 - 35) / 5 = 2.0.

Question 4

The ordinary arithmetic average is called the __________.

Accepted Answer

The answer of The ordinary arithmetic average is called the...

Question 5

A research article states that "At the time of the study, the mean age of first-year college students at Wayne University was 17.6 (3.57). The number in parentheses likely represents:

Accepted Answer

The number in parentheses likely represents the standard deviation. It is common to display the mean and standard deviation together in this format.

Question 6

Although __________ and __________ are often provided in research articles (in the text or tables), _________ are rarely reported.

Accepted Answer

Means and standard deviations are often reported in research articles, and Z scores are sometimes included, but range and outliers are rarely reported. T scores are also not typically included in research articles.

Question 7

A person's raw score is 7, the mean is 13, and the standard deviation is 3. What is the person's Z score?

Accepted Answer

The Z-score is calculated as (X - mu) / sigma, where X is the raw score, mu is the mean, and sigma is the standard deviation. In this case, X = 7, mu = 13, and sigma = 3. Therefore, the Z-score is (7 - 13) / 3 = -2.

Question 8

The mean of the scores 2, 2, 2, 6 is __________.

Accepted Answer

The answer of The mean of the scores 2, 2,...

Question 9

Who was the behavioral psychologist opposed to the use of statistics in psychology?

Accepted Answer

B.F. Skinner was a behavioral psychologist who opposed the use of statistics in psychology. He believed that behavior should be studied based on its direct observation and manipulation, rather than through statistical analysis.

Question 10

Donald's score on the statistics test was +1.25. This means that he scored:

Accepted Answer

The mean score is 0, and assuming a standard deviation of 1, a score of +1.25 would be more than one standard deviation above the mean.

Question 11

A raw score is equal to the:

Accepted Answer

A raw score can be converted from a Z score by multiplying the Z score by the standard deviation and then adding the mean. This is the reverse process of standardizing a score.

Question 12

In relation to the other people in their classes, who had the better exam score?

Accepted Answer

As Zoey's score was 80% and Lee's score was 70%, Zoey had the better exam score.

Question 13

For a particular group of scores, M = 15 and SD = 3. Provide the raw score for a Z score of 7:

Accepted Answer

The formula for converting a Z score to a raw score is: Raw score = M + (Z * SD). Here, M = 15, Z = 7, and SD = 3. So, Raw score = 15 + (7 * 3) = 36.

Question 14

A __________ describes a particular score in terms of where it fits into the overall group of scores.

Accepted Answer

A Z score describes a particular score in terms of where it fits into the overall group of scores by indicating how many standard deviations it is above or below the mean.

Question 15

For a particular group of scores, M = 20 and SD = 5. What is the Z score for a raw score of 10?

Accepted Answer

Z-score formula is given by:
Z = (X - M) / SD

Substituting the given values,

Z = (10-20) / 5 = -2

But as we require the absolute value of Z, the final answer is 2.

Question 16

A Z score of 2.0 came from a distribution with a mean of 80 and a standard deviation of 10. What is the raw score?

Accepted Answer

A Z score of 2.0 means the raw score is 2 standard deviations above the mean. With a mean of 80 and a standard deviation of 10, the raw score is 80 + (2 * 10) = 100.

Question 17

All of the following are true statements about a Z score EXCEPT:

Accepted Answer

A Z score is negative if the actual score falls below the mean and positive if it falls above the mean. Therefore, statement C is false.

Question 18

Qualitative research techniques are likely to involve each of the following EXCEPT:

Accepted Answer

Qualitative research techniques typically focus on collecting non-numerical data through methods such as lengthy interviews, focus groups, and observations of individuals in natural settings. Quantitative methods, which involve statistical analysis of numerical data, are not typically used in qualitative research.

Question 19

Whose name is associated with behaviorism and opposition to the field of statistics on the basis that important information may be lost by averaging the results of a number of cases?

Accepted Answer

B.F. Skinner is the psychologist associated with behaviorism and opposition to the field of statistics. He believed that important information may be lost by averaging the results of a number of cases.

Question 20

Which of the following is NOT an advantage of Z scores?

Accepted Answer

Z scores do not provide information about the shape of the distribution of scores, only their position relative to the mean.
