Scatterplot, английский
A scatterplot is a way to visualize bivariate data. a scatterplot is a plot of pairs of measurements on a collection of "individuals" (which need not be people). for example, suppose we record the heights and weights of a group of 100 people. the scatterplot of those data would be 100 points. each point represents one person`s height and weight. in a scatterplot of weight against height, the x-coordinate of each point would be height of one person, the y-coordinate of that point would be the weight of the same person. in a scatterplot of height against weight, the x-coordinates would be the weights and the y-coordinates would be the heights.

Point of averages, английский
In a scatterplot, the point whose coordinates are the arithmetic means of the corresponding variables. for example, if the variable x is plotted on the horizontal axis and the variable y is plotted on the vertical axis, the point of averages has coordinates (mean of x, mean of y).
Double-blind, double-blind experiment, английский
In a double-blind experiment, neither the subjects nor the people evaluating the subjects knows who is in the treatment group and who is in the control group. this mitigates the placebo effect and guards against conscious and unconscious prejudice for or against the treatment on the part of the evaluators.
