If a student has a percentile rank of 80 on a test, what does this indicate about their performance?

Match each psychology research scenario with the correct percentile rank for the target score.

In a psychological study with 100 participants, a score of 25 has a percentile rank of 50. If the researcher doubles the sample size by adding 100 new participants who all score strictly lower than 25, the new percentile rank for a score of 25 will be 75.

A researcher is comparing the relative standing of four participants across different psychological assessments. Evaluate the percentile rank for each participant based on the count of scores falling below them and the total number of scores in each distribution. Arrange the participants in order from the highest percentile rank (at the top) to the lowest percentile rank (at the bottom).

To calculate a percentile rank, one counts the number of scores in a distribution that fall below a specific value and converts that count into a percentage of the total number of scores.

A researcher evaluates the results of a motivation scale administered to $120$ students and finds that a score of $50$ has a percentile rank of $70$. Based on the standard calculation for percentile ranks, which statement best explains how the researcher determined this result?

In a distribution of 50 scores on a social anxiety scale, a researcher determines that 15 scores are strictly lower than a score of 20. The percentile rank for the score of 20 is _____.

Match each research scenario to its correctly computed percentile rank. For each scenario, count the number of scores that fall strictly below the target score, divide by the total number of scores, and multiply by $100$.

In a distribution of $40$ self-regulation scores, a researcher reports that a score of $55$ has a percentile rank of $75$. The researcher subsequently finds that $10$ additional participants' scores were inadvertently excluded from the dataset; all $10$ of the omitted scores fall strictly below $55$. After incorporating the omitted scores into the dataset, the updated percentile rank for a score of $55$ is _____.

A research team wants to determine which of four participants demonstrated the strongest relative performance on their respective psychological assessments, each administered to a different sample. Compute each participant's percentile rank and order them from strongest (1 = highest percentile rank) to weakest (4 = lowest percentile rank).
