The degree of agreement or disagreement is given a numerical value and a total can be calculated.Line graphA graphical presentation that plots means for a variable over a period of time.Longitudinal studiesStudies conducted by following subjects over a period of time, with data collection occurring at prescribed intervals.Magnet statusA designation for organizations that have characteristics that make them attractive to nurses as workplaces.Magnitude of effectThe size of the differences between experimental and control groups; itsupports clinical significance of the findings.Margin notesReflective notes manually inserted into qualitative transcripts that describe ideas about meaning that occur to the analyst during reading.MaturationA threat to internal validity because the changes that occur in subjects do not happen as a result of the intervention, but rather because time has passed.
MeanThe average; a measure of central tendency.MeasurementDetermination of the quantity of a characteristic that is present; it involves assigning of numbers or some other classification.
