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...

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...

-It would not be appropriate to use the Mann–Whitney U test when: a researcher is comparing two independent populations. the dependent variable is measured at the ordinal level. the assumptions for an independent-samples t test are not met. a researcher is comparing three or more groups on a normally distributed dependent variable. -Kia assesses people's levels of gratitude and stress that occur naturally to determine if a relationship exists between the two variables.

please answer them all.
When designing a sound scientific experiment, which of the following guidelines should be followed? Isolating one independent variable makes it simpler to evaluate for a causal relationship. Correlational data can be used to prove a hypothesis. The control group is ignored during comparison. Constants are not always necessary.

Question 25 2 pts A researcher believes that recall of verbal material differs with the level of processing. He divided his subjects into three groups and manipulated the level of processing they used when learning a list of words. In the 'low processing group, participant read each word and were instructed to count the number of letters in the word. In the "medium processing group, participants were asked to read each word and think of a word that rhymed. In...
