🔬Independent and dependent variables

An experiment is structured around manipulating a controlled change in an independent variable and then measuring a dependent variable to test whether the outcome changes due to a hypothesized cause.

Independent Variable Manipulation
The value of an independent variable is that the researcher can meaningfully change its level and thereby test whether this leads to a systematic change in the result.
Roles of Variables in Experimental Design
Errors in an experiment often begin with confusion of the roles of variables, when a control factor, an outcome, or a possible confounder are mixed in the same design.
Measuring the dependent variable
The dependent variable should be measured to capture the effect of interest rather than extraneous noise, convenient surrogates, or procedural artifacts.

# Независимая и зависимая переменные Эксперимент строится вокруг управляемого изменения независимой переменной и последующего измерения зависимой, чтобы проверить, меняется ли результат вслед за предполагаемой причиной. Эта тема раскрывает узел "Эксперимент" и нужна для того, чтобы карта не заканчивалась общим названием без внутренней структуры.
