Dichotomous format refers to a test item format in which there are two (2) alternatives for each item.
In psychology, the term "dichotomous format" refers to a type of measurement or assessment that involves two categories or options. Dichotomous format is often used in survey research, in which respondents are asked to choose between two options or to classify themselves as belonging to one of two categories.
For example, a survey might use a dichotomous format by presenting respondents with a list of statements and asking them to indicate whether they agree or disagree with each statement. This type of measurement would be considered dichotomous because it involves two categories (agree or disagree) and does not allow for any other responses.
Another example of a dichotomous format might be a survey that asks respondents to classify themselves as either extroverted or introverted. This type of measurement would be considered dichotomous because it involves two categories (extroverted or introverted) and does not allow for any other responses.
Overall, the term "dichotomous format" refers to a type of measurement or assessment that involves two categories or options and does not allow for any other responses.
