As an expert in the field of educational measurement and assessment, I'd like to provide a comprehensive explanation of what a "raw score" means in the context of testing and evaluation.
A raw score is the actual numerical value that represents a person's performance on a test or assessment without any adjustments or transformations. It is the most basic form of a test score, reflecting the number of correct answers or the total points earned by the individual. The concept of a raw score is fundamental to understanding the various types of scores that can be derived from a test.
Here are some key points about raw scores:

1. Direct Measurement: A raw score is a direct measurement of a test taker's performance. It is the sum of the points for correct answers or the count of accurate responses.

2. Unaltered: The term "raw" implies that the score has not been changed or modified in any way. It is the original score as it was recorded.

3. Individual Performance: Each person's raw score is unique to them and reflects their individual performance on the test.

4. Comparison: Raw scores are often used for comparison purposes. For instance, educators may compare a student's raw score to the class average to understand how the student performed relative to their peers.

5. Data Set: When you collect raw scores from all participants in a test, you create a raw data set. This set can be analyzed to understand the overall performance of the group and to identify patterns or trends.

6. Interpretation: While raw scores are straightforward, they may not always be the most informative for interpreting a test taker's abilities. For example, a raw score of 85 on one test might indicate a high level of proficiency, while the same score on a more difficult test could indicate a lower level of proficiency.
7.
Standardization: In some cases, raw scores are converted to standardized scores to allow for comparison across different tests or different forms of the same test. This process involves mathematical transformations that take into account the difficulty of the test and the performance of the group.
8.
Equating: Sometimes, different forms of a test are used, and it's necessary to ensure that the scores are equivalent. This process, known as equating, adjusts raw scores so that they are comparable.
9.
Confidentiality: It's important to maintain the confidentiality of raw scores, as they can be sensitive information about a person's academic performance.
10.
Use in Decision Making: Raw scores are often used in decision-making processes, such as determining a student's grade or eligibility for certain programs. However, they should be interpreted carefully and in the context of the test's purpose and the individual's circumstances.
Understanding raw scores is crucial for educators, test developers, and anyone involved in the assessment of learning outcomes. It provides a clear, unadulterated view of a test taker's performance, which can then be used as a basis for further analysis and informed decision-making.

A raw score is an unaltered measurement. For example, let's say you took a test in class and scored 85. This is a raw score, an unaltered measurement of how you did. You scored 85. A raw data set is a collection of raw scores from all the tests.read more >>
