A research question is "a question that a research project sets out to answer". [1] Choosing a research question is an essential element of both quantitative and qualitative research. Investigation will require data collection and analysis, and the methodology for this will vary widely.
Statistical tests are used to test the fit between a hypothesis and the data. [1] [2] Choosing the right statistical test is not a trivial task. [1]The choice of the test depends on many properties of the research question.
A suggestive question is one that implies that a certain answer should be given in response, [1] [2] or falsely presents a presupposition in the question as accepted fact. [3] [4] Such a question distorts the memory thereby tricking the person into answering in a specific way that might or might not be true or consistent with their actual feelings, and can be deliberate or unintentional.
The cancellation of variables common to undominated pairs can be illustrated as follows. When comparing alternatives 121 and 112, for example, a1 can be subtracted from both sides of a1 + b2 + c1 vs a1 + b1 + c2. Similarly, when comparing 221 and 212, a2 can be subtracted from both sides of a2 + b2 + c1 vs a2 + b1 + c2.

An example of Neyman–Pearson hypothesis testing (or null hypothesis statistical significance testing) can be made by a change to the radioactive suitcase example. If the "suitcase" is actually a shielded container for the transportation of radioactive material, then a test might be used to select among three hypotheses: no radioactive source ...
A few online and downloadable software tools help automate the ACH process. These programs leave a visual trail of evidence and allow the analyst to weigh evidence. PARC ACH 2.0 [17] [18] was developed by Palo Alto Research Center (PARC) in collaboration with Richards J. Heuer, Jr. It is a standard ACH program that allows analysts to enter ...
