Recall bias is a type of measurement bias, and can be a methodological issue in research involving interviews or questionnaires. In this case, it could lead to misclassification of various types of exposure . [ 2 ]
The effect(s) of such misclassification can vary from an overestimation to an underestimation of the true value. [4] Statisticians have developed methods to adjust for this type of bias, which may assist somewhat in compensating for this problem when known and when it is quantifiable. [5]
An F-score is a combination of the precision and the recall, providing a single score. There is a one-parameter family of statistics, with parameter β, which determines the relative weights of precision and recall. The traditional or balanced F-score is the harmonic mean of precision and recall:
Encoding processes can occur at three levels: visual form (the letters that make up a word), phonology (the sound of a word), and semantics (the meaning of the word or sentence). With relation to memory errors, the level of processing at the time of encoding and at the time of recall should be the same. [37]
Explanations include information-processing rules (i.e., mental shortcuts), called heuristics, that the brain uses to produce decisions or judgments. Biases have a variety of forms and appear as cognitive ("cold") bias, such as mental noise, [5] or motivational ("hot") bias, such as when beliefs are distorted by wishful thinking. Both effects ...
In free recall and serial recall, the modality effect is seen as simply an exaggerated recency effect in tests where presentation is auditory. In short-term sentence recall studies, emphasis is placed on words in a distractor-word list when requesting information from the remembered sentence.

It is a type of systemic bias. Language and educational issues can lead to a misunderstanding of the question by the respondent, or similarly, a misunderstanding of the response by the surveyor. Recall bias can lead to misinformation based on a respondent misrecalling the facts in question.
