Manipulation checks are measured variables that show what the manipulated variables concurrently affect besides the dependent variable of interest. In experiments, an experimenter manipulates some aspect of a process or task and randomly assigns subjects to different levels of the manipulation ("experimental conditions").
Blue-dot task, a check designed to detect participants who fail to read the instructions. After Oppenheimer et al. [1]. An instructional manipulation check, often abbreviated IMC, is a special kind of question inserted in a questionnaire among the regular questions, designed to check whether respondents are paying attention to the instructions.

If M-score is less than -1.78, the company is unlikely to be a manipulator. For example, an M-score value of -2.50 suggests a low likelihood of manipulation. If M-score is greater than −1.78, the company is likely to be a manipulator. For example, an M-score value of -1.50 suggests a high likelihood of manipulation.
Read on for a step-by-step example of a check filled out from top to bottom. 1. Write the Date. Write the correct date in the date label near the upper right corner of the check. Use the current ...
For example, if a dataset of patients records their age and sex, then a researcher can consider grouping them by age and check if the illness recovery rate is correlated with age. If it does not work, then the researcher might check if it correlates with sex. If not, then perhaps it correlates with age after controlling for sex, etc.
For example, you might make out a check on March 5 but write March 15 on the date line. This often is done if account funds won’t be available until a specified future time.
An example of abstraction is to ignore the values of non-Boolean variables and to only consider Boolean variables and the control flow of the program; such an abstraction, though it may appear coarse, may, in fact, be sufficient to prove e.g. properties of mutual exclusion.
Inspection is a verification method that is used to compare how correctly the conceptual model matches the executable model. Teams of experts, developers, and testers will thoroughly scan the content (algorithms, programming code, documents, equations) in the original conceptual model and compare with the appropriate counterpart to verify how closely the executable model matches.
