A variable list keyed to questionnaire items enables the identification

Question : A variable list keyed to questionnaire items enables the identification : 2153851

TRUE/FALSE. Write 'T' if the statement is true and 'F' if the statement is false.

1) A variable list keyed to questionnaire items enables the identification and examination of questionnaire content to ensure proper coverage, balance, and non-duplication of items.

2) Data management is concerned with the process by which the raw data gathered by some instrument or measurement are converted into numbers for analysis purposes.

3) Prior to the actual coding, the questionnaires must be edited.

4) Programming is the assignment of numerical values to responses (information) gathered by a research instrument.

5) A programming ledger is a guidebook for numerically classifying each question to be coded.

6) Data checking involves checking the work of coders for accuracy.

7) Data verification or cleaning involves double checking the data file in search of errors, many of which are inevitable despite the conscientiousness of workers.

8) The keyboard entry technique is the most widely used means of inputting data.

9) Rates, proportions, percentages, and ratios are meaningful ways of standardizing data so that useful comparisons can be made between unequal populations.

10) Recidivism rate is the number of crimes divided by population, per 100,000 population.

11) Crime clocks are a highly accurate means of depicting crime change due to their ability to account for population growth.

12) Pie charts are presentations of quantitative data in a summary or uniform fashion.

13) Bivariate tables, or those in which there is a two-variable cross tabulation, examine how one variable influences the other.

14) Elaboration refers to the process of introducing or controlling for third variables (control or test factors) by subclassifying original tables.

15) Explanation takes place when the partial tables replicate or reproduce the relationship in the original table.

16) Replication occurs when the relationship observed in the original bivariate table weakens or disappears in the partial tables.

17) Interpretation occurs when the partial table relationships weaken or disappear and the control variable is an intervening one (occurs between X and Y).

18) Suppression takes place when relationships occur in the partial tables even though there is no original bivariate relationship.

19) Graphic or pictorial presentations include pie charts, bar graphs, and frequency polygons.

20) The major types of elaboration are: replication, specification, explanation, interpretation, and suppression.
