科学实验中的两个主要变量是自变量和因变量。以下是关于自变量的定义以及它是如何使用的:独立变量定义:自变量定义为在科学实验中改变或控制的变量。它代表了结果的原因或原因。自变量是实验者改变以测试其因变量的变量。自变量的变化直接导致因变量的变化。测量并记录对因变量的影响。常见拼写错误:独立变量。一位科学家通过打开和关闭灯来测试光明和黑暗对飞蛾行为的影响。自变量是光量,而蛾的反应是因变量。在确定温度对植物色素沉着的影响的研究中,自变量(原因)是温度,而色素或颜色的量是因变量(效果)。绘制独立变量。绘制实验数据时,自变量绘制在x轴上,而因变量记录在y轴上。保持两个变量直接的简单方法是使用首字母缩略词DRY MIX,它代表:响应变化的从属变量在Y轴上。 Manipulated或Independent变量位于X轴上

美国哥伦比亚大学论文代写:独立变量定义和示例

The two main variables in a science experiment are the independent variable and the dependent variable. Here’s the definition on independent variable and a look at how it’s used: Independent Variable Definition:An independent variable is defines as the variable that is changed or controlled in a scientific experiment. It represents the cause or reason for an outcome. Independent variables are the variables that the experimenter changes to test their dependent variable. A change in the independent variable directly causes a change in the dependent variable. The effect on the dependent variable is measured and recorded. Common Misspellings: independant variable. A scientist is testing the effect of light and dark on the behavior of moths by turning a light on and off. The independent variable is the amount of light and the moth’s reaction is the dependent variable. In a study to determine the effect of temperature on plant pigmentation, the independent variable (cause) is the temperature, while the amount of pigment or color is the dependent variable (the effect). Graphing the Independent Variable.When graphing data for an experiment, the independent variable is plotted on the x-axis, while the dependent variable is recorded on the y-axis. An easy way to keep the two variables straight is to use the acronym DRY MIX, which stands for: Dependent variable that Responds to change goes on the Y axis. Manipulated or Independent variable goes on the X axis
