11.A test which yields consistent scores when a person takes two alternate forms of the              test is __________. a)unreliable b)valid c)reliable d)inconsistent 12._________ assesses the question, “Does the test adequately measure what it purports              to measure?” a)reliability b)validity c)level of measurement d)the correlation coefficient 13.In order to understand fully which attributes are being measured by a test, one must              examine the ________ of the test. a)consistency b)reliability c)validity d)measurement error 14.The most basic, yet most central, statistical concept for psychological measurement is a)correlation b)prediction c)variability d)factor analysis 15.Co-variance is the concept that is most important when dealing with a)correlation b)modality c)variability d)both a and b 16.The average score on a test is a) the mode b)the range c)the median d)the mean 17.The average of the squared deviation scores is a)the mean b)the standard deviation c)the variance d)the range 18.If the variance on a test is small, we know that a)people had similar scores on the test b)people had scores close to the mean score c)the standard deviation will be small d)all of the above 19.Correlations are often illustrated by using a)matrix plots b)coordinate plots c)frequency plots d)scatter plots 20.If an increase on one variable is associated with an increase on another variable, the              variables are a)positively correlated b)highly correlated c)negatively correlated d)not correlated 21.If a large increase on one variable is associated with a large decrease on another              variable a)the variables are highly positively correlated b)the correlation coefficient will be large and positive c)the correlation coefficient will be large and negative d)the correlation coefficient will be small and negative 22.An attempt to identify the basic underlying variables which account for the correlations              between actual test scores is done statistically through a)multiple regression b)linear modeling c)factor analysis d)the correlation coefficient 23.If students at Lincoln High School receive Verbal Aptitude Test (VAT) scores with a              mean of 100 and a standard deviation of 7.6, while students at Washington High School              receive VAT scores with a mean of 120 and a standard deviation of 2.8, we know that a)students at Washington High School are smarter than students at Lincoln High              School b)individual students at Lincoln High School had more similar VAT scores than did individual students at Washington High School c)the test may be unfair because of the large difference between scores of Lincoln              High School students and Washington High School students d)there was less variability on the scores received by students at Washington High                           School 24.In a(n) ______ factor analysis, factors are defined in terms of the specific hypothesis              being tested. a)exploratory b)confirmatory c)”seat of the pants” d)none of the above
