The variance is a measure of dispersion of scores around some measure of central tendency. The variance is the standard deviation squared. A popular IQ test has a standard deviation (SD) of 15. A counselor would expect that if the mean IQ score is 100 then, a personal with a n IQ of 122 would fall within: a. + or - 1 SD of the mean b. the average IQ range c. an IQ score which is more than 2 SD above the mean d. + or -2 SD of the mean
d. + or - 2SD of the mean The great the SD, the greater the spread of scores
90
The standard deviation (SD) is the square root of the variance. A z-score of +1would be the same as a. 1 SD above the mean b. 1 SD below the mean c. the same as a so called t-score d. the median score if the population is normal
a. 1 SD above the mean Z SCORES are the SAME as standard deviations! they are often called "standard scores"
91
Z-scores (also called standard scores) are the same as standard deviations, thus a z-score -2.5 means a. 2.5 SD below the mean b. 2.5 SD above the mean c. a CEEB score of 500 d. -.05% of the population falls within this area of the curve
a. 2.5 SD below the mean (CEEB ranges from 200 to 800 with a mean of 500, SD of 100)
92
A t-score is different from a z-score. A z-score is the same as the SD. A t-score, however, has a mean of 50 with every 10 points landing at a SD above or below the mean. Thus a t-score of 60 would equal +1 SD while a t-score of 40 would be a. -2 SD b.-1 SD c. a z-score of +2 d. a z-score of +1
b. -1 SD
93
An IQ score on an IQ test which was 3 SD above the mean would be a. about average b. slightly below the norm for adults c. approximately 110 d. very superior
d. very superior
94
A playykurtic distribution would approximately look like: a. the upper half of a bowling ball b. the normal distribution c. the upper half of a hot dog, lying on its side over the abcisssa d. a camel's back
c. the upper half of a hot dog, lying on its side over the abcisssa kurtosis= the peakedness of a frequency distribution (A platykurtic distribution is flatter and more spread out than the normal curve (like a plate) a leptokurtic distribution is tall, thin, and peaked = Superman lept-over the peaks in a single bound!)
95
Tet scores on an exam that fell below 3 SD of the mean or above 3 SD of the mean could be described as a. extreme b. very typical or within the average range c. close to the mean d. very low scores
a. extreme (very high or very low)
96
In WWII the Air Force used stannic scores as a measurement. STANINE SCORES DIVIDE THE DISTRIBUTION INTO 9 EQUAL INTERVALS WITH STANINE 1 AS THE LOWEST 9TH AND 9 AS THE HIGHEST. IN THIS SYSTEM, 5 IS THE MEAN. Thus the Binet IQ of 101 would fall in the Stanine a. 1 b. 9 c. 5 d. 7
c. 5
97
There are 4 basic measurement scales: the nominal, the ordinal, the interval, and the ratio. The nominal scale is strictly a qualitative scale. It is the simplest type of scale. *It is used to distinguish logically separated groups.* Which of the following illustrates the function of the nominal scale? a. a horse categorized as a second-place winner in a show b. a DSM or ICD diagnostic category c. An IQ score of 111 d. The weight of an Olympic barbell set.
b. a DSM or ICD diagnostic category *A nominal scale has no true zero point and does not indicate order Memory device that shows increasing complexity "NOIR" Nominal, Ordinal, Interval, & Ratio)
98
The ordinal scale rank orders variables, though the *relative distance between the elements and is not always equal*. An example of this would be: a. a horse is categorized as a second-place winner in a race b. an IQ score of 111 c. the weight of an Olympic barbell set d. a temperature of 78 degrees Fahrenheit
a. a horse is categorized as a second-place winner in a race *The ordinal scale provides relative placement or standing but does not delineate absolute differences *Adding, subtracting, multiplying or dividing makes no sense with this scale. It simply ranks ORDER
99
The interval scale has numbers scaled at equal distances but has no absolute zero point. Most test used in school fall into this category. You can add and subtract using interval scales but cannot multiply or divide. An example of this would be that a. an IQ of 70 is 70 points below an IQ of 140, yet a counselor could not assert that a client with an IQ of 140 is twice as intelligent as a client with an IQ of 70 b. a 20 lb weight is half as heavy as a 40 lb weight c. a first-place runner is three times as fast as the third-place finisher d. a baseball player with a 9 on his uniform can get 9 times more hits than a player with 1
a. an IQ of 70 is 70 points below an IQ of 140, yet a counselor could not assert that a client with an IQ of 140 is twice as intelligent as a client with an IQ of 70 *IQ tests provide interval measurement.
100
A ratio scale is an interval scale with a true zero point. Ratio measurements are possible using this scale. Addition substation, multiplication, and division all can be utilized on a ratio scale. In terms of counseling research a. the ratio scale is the most practical. b. all true studies utilize the ratio scale c. a and b d. the most psychological attributes cannot be measured on a ratio scale
d. the most psychological attributes cannot be measured on a ratio scale
101
Researchers often utilize naturalistic observation when doing ethological investigation of children's behavior. In this approach a. the researcher manipulates the IV b. the researcher manipulates the IV and the DV c. the researcher does not manipulate or control variables d. the researcher will rely on a 2x3 factorial design
c. the researcher does not manipulate or control variables. (d= first variable has 2 levels (ex. male and female) and second variable has 3 levels = 2x3 factorial design)
102
The simplest form of descriptive research is the XXX which requires a questionnaire return or completion rate of XXX to be accurate. a. survey, 5% b. survey, 10-25% c. survey, 50-75% d. survey, 95%
c. survey, 50-75% Survey problems include: poor construction of the instrument, a low return rate, and the face that often subjects are not picked at random and thus are not representative of the population
103
A researcher gives a depressed patient a sugar pill and the individual's depression begins to lift. This is known as: a. the Hawthorne effect b. the Halo effect c. the placebo effect d. the learned helplessness syndrome
c. the placebo effect (a "nocebo" has a negative effect such as when a doctor comments that a person has only a few weeks to live due to an illness)
104
A researcher notes that a group of clients who are not receiving counseling , but are observed in a research study, are improving. her hypothesis is that the attention she has given them has been curative. The best explanation of their improvement would be: a. the Hawthorne effect b. the Halo effect c. the Rosenthal Effect d. a Type II error in the research
a. the Hawthorne effect (sometimes known as the observer effect)
105
An elementary school counselor tells the third-grade teacher that a test revealed that certain children will excel during the school year. In reality, no such test was administered. Moreover, the children were unaware of the experiment. By the end of the year, all of the children who were supposed to excel, did. This would best be explained by a. the Hawthorne effect b. the Halo Effect c. the Rosenthal effect (or experimenter expectancy effect) d. observer bias.
c. The Rosenthal effect=experimenter expectancy effect
106
A panel of investigators discovered that a researcher who completed a major study had unconsciously rated attractive females as better counselors. This is an example of: a. the Hawthorne effect b. the Halo effect c. the Rosenthal effect d. trend analysis (ANOVA can help with)
b. the Halo effect (occurs when a trait which is not being evaluated influences a researchers rating)
107
All of the following describe the analysis of covariance technique except: a. it is a correlation coefficient b. It controls for sample differences which exist. c. It helps to remove confounding extraneous variables. d. It statistically eliminates differences in average values influenced by covariates
a. it is a correlation coefficient (the ANCOVA is often referred to as "an adjusted average", it aims to eliminate extra factors that make ID less alike)
108
Three years ago an inpatient addiction treatment center in a hospital asked their clients if they would like to undergo an archaic form of therapy created by Wilhelm Reich known as "vegotherapy". Half people said yes, half stuck to a tried and true program. Outcome data on their drinking was compiled at the end of seven weeks. Three years later, someone compared the two grou9ps based on their drinking behavior at the end of the seven weeks using a t-test. This study could be best described as: a. correlation research b. a true experiement c. a cohort study d. causal comparative research
d. causal comparative research cohort study= ppl born at the same time or who lived through something significant (vietnam war, great depression etc)
