These outcomes are the experiment’s dependent variables.

这些结果是实验的因变。

Our dependent variables are the volume of employment and the national income (or national dividend) measured in wage-units.

我们的因变是就业工资单位衡的民收入（或民红）。

But you can also have variables that you believe are affected by changes in your independent variable; these are your dependent variables.

但是您也可拥有您认为受自变变化影响的变；这些是你的因变。

So we have one independent variable – receiving the voucher or not – and a bunch of possible dependent variables, like earnings, education, and health outcomes.

所我们有一个自变——是否收到代金券——及一堆可能的因变，比如收入、教育健康结果。

To begin with, it may be useful to make clear which elements in the economic system we usually take as given, which are the independent variables of our system and which are the dependent variables.

首先，弄清楚我们通常认为经济系统中的哪些要素是给定的，哪些是我们系统的自变，哪些是因变可能是有用的。
