مفهوم الارتباط والسببية مع مثال Correlation Vs. Causality with Example 台灣

يشرح هذا المقطع الفرق بين الارتباط والسببية مع مثال عددي وبياني ... Correlation and Causality with a numerical Example #Correlation and #causality are two statistical concepts that are often misunderstood or used interchangeably, but they have distinct meanings. Correlation refers to a relationship between two variables where changes in one variable are associated with changes in the other variable. In other words, two variables are said to be correlated when they tend to move in the same direction or opposite direction. However, correlation alone does not imply causality. Just because two variables are correlated does not mean that one variable causes the other. Causality, on the other hand, refers to a relationship where one variable directly affects the other variable. In other words, one variable is said to cause the other when changes in the first variable directly result in changes in the second variable. Causality implies correlation, but correlation does not imply causality. Here's an example to illustrate the difference between correlation and causality: Suppose we observe a strong positive correlation between ice cream sales and crime rates in a particular city. We might be tempted to conclude that ice cream consumption causes crime. However, this is a spurious correlation because ice cream sales and crime rates are not causally related. Instead, both variables are likely influenced by a third variable, such as temperature. In this case, higher temperatures lead to increased ice cream sales as well as increased crime rates. To establish causality, we would need to conduct a carefully designed experiment where we manipulate the ice cream consumption of a group of people and observe changes in their criminal behavior. Without such an experiment, we cannot conclude that ice cream consumption causes crime, despite the observed correlation.
