THE Q U E S T I O N N A I R E 1 33 Closed- vs. open-ended questions and levels of measurement Our selection of closed- or open-ended questions carries implications for the level of measurement we achieve in our survey items. Focus groups are guided group discussions of selected topics. Indeed, the insistence on replication is simply the skeptical "show me" attitude of science coming full circle - if the findings are true, they should show up time after time under similar research conditions. Observing Ourselves: Essays in Social Research. In posing the question of internal validity (aka causal validity) we are asking if the overall research plan or research design is really capable of detecting causal relationships when they exist. Once we are familiar with the idea of external validity, we can see the value of replication in a slightly different light. Wiltz, John E. 1973. Questions that don't follow rules of good grammar can also prove difficult for respondents. Poor Americans were not included in the Digest poll and poor Americans were solidly behind Roosevelt and his New Deal. Time-Based Knowing: Traditional Knowledge Credential-Based Knowing: Authoritative Knowledge More Risky Knowledge Sources: Common Sense and Intuition Science as a Trustworthy Way of Knowing Goals of Research Using Research Methods to Become Critical Consumers of Information 2 Ethics: It's the Right Thing To Do Research Should Not Cause Harm to Subjects Researchers Should Obtain the Informed Consent of Subjects Researchers Should Respect Subjects' Privacy Researchers Should Avoid Conflicts of Interest Ethical Reporting: The Whole Truth and Nothing but the Truth? The numbers attached to values might also indicate a ranking or ordering of the values - the values attached to the number 1 might be less than the values attached to the number 2 which in turn might be less than the values attached to the number 3. San Francisco Chronicle, December 8. These correction terms are formally known as confidence intervals - i.e., we are confident that the true population value actually falls somewhere in this range of numbers. If you look at the numbers attached to each of these values they indicate an increasing magnitude of the values - i.e., an increasing amount of formal education. Have those individuals from the 2002 sample changed their views? How do they occupy the space? Then, we tested for common method variance (CMV) with a CFA model wherein all the items loaded on the respective factors and a common method factor (Podsakoff et al., 2003).

One of the most notorious examples of the privacy dilemma in a public research setting is offered by Laud Humphreys' study (1969) of tearooms (public restrooms used for impersonal homosexual encounters). Some help in finding the right statistical tool for a particular data set can be found at Bill Trochim's "Selecting Statistics": http://trochim.human.Cornell, edu/selstat/ssstart.htm. However, recent studies have started to explore the potential positive influence of authoritarian leadership (Huang et al., 2015; Tian and Sanchez, 2017), suggesting that the mechanisms through which authoritarian leadership influences employee outcomes still require further investigation. Research procedures offer great safeguards against error, but error can still make its way into scientific findings. Retrospective questions about your childhood experiences with physical discipline can be used to investigate a causal connection with your later disciplinary practices as a parent. See the link "How Polls are Conducted" on the Gallup homepage: http://www.gallup.com/. Go to http://www.americanheart.org and follow the "Health Tools" link. Replication To regard findings as true and reliable, science insists that those findings occur more than once. Third, we have made assumptions about the moderating role of individual power distance. Evidence that is obtained in an unsystematic way is regarded as tainted or problematic; it is seen as less trustworthy. SPSS (Statistical Package for the Social Sciences) We have covered quite a few important statistical tools in this chapter and you may be feeling like your boat is about to go down in the rough sea of statistics. With field research, the social investigator directly observes people/events in their natural settings.

We consider this question next. Broaden your knowledge with SEO resources for all skill levels. One researcher might define alienation as a loss of involvement in the activity of working. While small samples can adequately represent homogeneous populations (remember, a sample of one is all that's needed to perfectly represent a totally homogeneous population), diverse populations require larger samples. What's the probability that a score falls between 72 and 88?

Would the tips work well in a research setting? A measure is considered reliable if it yields the same results each time it is used, assuming, of course, that there's been no real change in the variable being measured. Using samples to make accurate generalizations about populations is a central concern of good sampling. The program takes a look at what has happened in the past century by looking through the "lens of data and measurement." option. In the final analysis, science demands redundancy. Well, in the five years between the two waves of the study, new environmentally astute students may have entered Whatsamatter U (and consequently show up in the 2007 sample), while "old" environmentally neutral students may have graduated from Whatsamatter U (and are missing from the 2007 sample). 1998.

For instance, some see easy access to guns as a cause of school violence. ed. A Gentle Guide to This concern with the ability to generalize from small to larger groups of similar elements is referred to as sample generalizability. This research design offers us the best chance of correctly identifying the causal connections between independent and dependent variables. All rights reserved. An upper-class bias was produced in their sampling technique - only the wealthiest Americans in 1936 owned phones and automobiles. Knowledge of the German building stock is largely based on census data and annual construction statistics.

In contrast, Spanish-speaking women undergoing cesarean delivery in a high-technology public hospital in Texas are, due to their limited English, only minimally able to interact with hospital staff.

Ratio level measures have true and meaningful zeros; interval level measures do not. Palm pilots, billboards, and information kiosks also keep us in the know. These findings support Hypotheses 1 and 2. Random assignment assures that the same kind of people are found in both groups and the experimental group won't wind up with more motivated (desperate to quit) participants than the control group. Consequently, the researcher's ability to eliminate rival explanations will ultimately depend on how thoughtful and diligent the researcher is about including survey questions about pertinent C variables. If we're "up for it," the stream of information can go on 24/7. Anyone who isn't interested in faithfully recording field notes should not be doing field research. As you read through the example, think about whether or not the researcher has provided enough detail to allow us to execute this measure on our own: Pieces of tape were placed unobtrusively on the sidewalk leading into the intersections at intervals of 1 foot or less from the curb, 2 feet from the curb, and 3 feet or beyond.
