TRUE/FALSE feasibility is a synonym for validity and objectivity is a synonym for reliability

FALSE

TRUE/FALSE in a data set, you must only have one value for each of the following: mean, median, and mode

FALSE

TRUE/FALSE criterion referenced scores allow for percentile equivalents to be calculated, while normative referenced scores allow for performance standards

FALSE (opposite)

TRUE/FALSE you have a baby. you take your baby to the doctor. the doctor tells you to refer to the graph provided to you for this exam. the doctor tells you, you are in the 10th percentile for height. expressing height in this way using the chart provided is a way of expressing your height using a criterion referenced standard

FALSE it's a norm referenced standard because you are comparing differences between individuals

TRUE/FALSE the shape of a distribution refers to the peakedness of a histogram, while the kurtosis refers to the skewness of a histogram

FALSE kurtosis=peakedness shape=skewness

TRUE/FALSE a distribution described as platykurtic can have the same mean as leptokurtic distribution

TRUE

TRUE/FALSE in some instances, the same data can be used for both formative and summative assessments

TRUE

TRUE/FALSE it doesn't matter whether a z score is positive or negative, the score from the table is the same, while the percentile is different

TRUE

TRUE/FALSE predictive and concurrent validity are subcategories of criterion validity

TRUE

TRUE/FALSE as the strength of a correlation coefficient increases, so too does the coefficient of determination

TRUE correlation coefficient is r, and coefficient of determination is r squared
