Answer the following questions: 1) Which of the following research designs poses a threat to internal validity called selection? a) one-shot case study b) one-group pretest-post test c) static-group comparison d) one-group 2) This type of research is considered a descriptive methodology in which results of interviews, observations, or questionnaires reveal what is happening at a particular occurrence. It involves recording, describing, analyzing, and interpreting conditions that presently exist. Comparisons and contrasts are attempted to reveal relationships between the non-manipulated...

Complete: Chapter 1 Problem Set 4. Dependent and independent variables Aa The following research studies consist of two or more groups of scores being compared. For each, decide whether the study is experimental or nonexperimental, and then identify the dependent, independent, or quasi-independent variables. A researcher would like to find out more about the determinants of college achievement. He conducts a study on 437 college students in which he measures their IQ levels and their grades in college courses. The...

1. The use of multivariate statistical techniques has become more commonplace largely due to the increasingly complex nature of research designs and related research questions. 2. A study appropriate for multivariate statistical analysis is typically defined as one with several dependent variables (DVs). The basic distinction between experimental and nonexperimental research designs is whether the levels of the independent variable(s) have been manipulated by the 3. 4. In nonexperimental research (eg, descriptive, correlational, survey, or causal- comparative designs), the researcher...

8) Suppose the correlation coefficient between two variables is -0.897. Does the dependent variable increase or decrease as the independent variable increases? O a. The dependent variable will decrease as the independent variable increases. O b. The dependent variable will remain constant as the independent variable increases. The dependent variable will remain constant as the independent variable increases. The dependent variable will increase as the independent variable increases.
