Dichotomization（二分法）is a statistical technique that involves dividing a continuous variable into two categories or groups based on a threshold value. The threshold value is usually determined by a priori knowledge or through trial and error.
For example, in a study on blood pressure, researchers may dichotomize the variable into "normal" and "high" categories based on a threshold value of 140 mmHg. This allows for easier analysis and interpretation of the data.
Usage: Dichotomization is a commonly used technique in medical research and social sciences, particularly in studies where the outcome variable is binary in nature. It is also used in marketing research, where continuous variables such as age or income are often dichotomized to better understand consumer behavior.
Examples:
The study dichotomized the variable of income into "low" and "high" categories based on a threshold value of $50,000 per year.
The researchers dichotomized the variable of depression into "present" and "absent" categories based on a threshold value of 10 on the Beck Depression Inventory.
Synonyms:Dichotomization is also known as binary categorization or binary classification.
Antonyms:There are no direct antonyms for dichotomization, but it is the opposite of continuous measurement, which involves measuring a variable across a range of values without dividing it into categories.
