A ___________________ is created when a researcher combines data (e.g. prices) from multiple items without weighing any of them more significantly than the others. a simple composite index b weighted composite index c simple index number d none of the above a simple composite index A simple composite index is created when a researcher gathers data from many different sources without weighing any data more significantly than any other data. Usually, this means that there is only one good or service being measured so that all of the information is weighted equally. What is a use of an index number? a To find books in the library b To assess the quantity or price of a good over time c To compare the price of two goods at a given moment d To compare other numbers to a certain number on a number line A simple composite index is created when a researcher gathers data from many different sources without weighing any data more significantly than any other data. Usually, this means that there is only one good or service being measured so that all of the information is weighted equally. ____________ counts all of the existing cases of a disease, while ______________ only counts new cases. a Prevalence and incidence b Rate and ratio analysis c Ratio analysis and rate d Incidence and prevalence a Prevalence and incidence A __________ measures one quantity in relation to another quantity. a proportion b incidence c rate d ratio d ratio Which of the following sentences is NOT true about the True Score Model? a An observed score is the score that is actually achieved on a test. b A true score is the best possible score an individual might achieve on a test. c Random Measurement Error should disappear as the number of tests increases. d Systematic Measurement Error means that there is a problem within the experiment itself. b A true score is the best possible score an individual might achieve on a test. Which one of the following is an example of Item Response Theory? a A coach gives his player a challenge to run around 6 cones in a certain amount of time. The player easily succeeds at this challenge.

T/F F Results-based management does not have many complex indicators, but rather it simplifies the data to better allow for a constant change of individual's roles as their performance is evaluated. Results-based management uses established terms to continuously measure and evaluate performance. T/F T From data mining, someone is able to make conclusions about the underlying causes of certain variables. T/F F. Data mining finds trends. As technology improves, there will be a greater amount of raw data. T/F T An index number is used to measure the change in quantity or price of a good or service over time. T/F T Index numbers are often used when measuring inflation of certain items, certain prices, or quantities and prices for societies as a whole. A simple composite index is often used to measure one good or service from many different sources. T/F T A simple composite index puts just as much weight on one piece of data as any other piece of data. Therefore, a simple composite index is often used to measure the same good or service across an industry Epidemiology is not very important to public health and medical professionals when making decisions. T/F F Prevalence measures the percent of a population with a disease while incidence measures the number of a population with a disease at a given time. T/F F. Although prevalence measures the percent of a population with a disease, incidence measures the percent of a population who has contracted the disease over a recent time period. Because criterion-referenced tests compare an individual to other individuals, it is extremely rare for an entire class to fail a test. T/F
