Psych 7 Final Set #5 Analysis of Research Result

Using bars to depict frequencies of responses, percentages, or means in two or more groups

Single number or value that describes the typical or central score among a set of scores

Index of how strongly two variables are related to each other

Outcome variable that is predicted in correlational research

Statistical measures that describe the results of a study; descriptive statistics include measure of central tendency (eg. mean), variability (eg. standard deviation), and correlation (eg. Pearson r)

Extent to which two variables are associated. in experimental research, the magnitude of the impact of the independent variable on the dependent variable

Arrangement of a set of scores from lowest to highest that indicated the number of times each score was obtained.

Graphic display of frequency distribution in which frequency of each score is plotted on vertical axis, with the plotted points connected by straight lines

Scale of measurement in which the intervals between numbers on the scale are all equal in size

Measure of central tendency, obtained by summing scores and then dividing the sum by the number of scores

Measure of central tendency, the middle score in a distribution of scores that divides the distribution in half

Measure of central tendency; the most frequent score in a distribution of scores

Correlation between one variable and combined set of of predictor variables

Scale of measurement with two or more categories that have no numerical (less than, greater than) properties

Scale of measurement in which the measurement categories form a rank order along a continuum
