Beyonce went through a battery of tests and received the following results: IQ – 115 Reading – 98th percentile Math – 44th percentile Self-Efficacy – T=71 Using the descriptors on the image at the top of the paper, how might we describe these scores? IQ: High Average Reading: Average Math: Average Self-Efficacy: Average 10: Average Reading High
The Correct Answer and Explanation is:
Correct Descriptors for Beyoncé’s Scores:
- IQ: High Average
- Reading: Very High (98th percentile)
- Math: Low Average (44th percentile)
- Self-Efficacy: Very High (T = 71)
Explanation
Beyoncé’s test results span several areas of cognitive and emotional functioning, and each score needs to be interpreted using standardized descriptors based on percentile ranks or T-scores. Here’s how we arrive at the correct interpretations:
- IQ – 115: High Average
IQ scores are typically based on a standard score where the average is 100 with a standard deviation of 15. A score of 115 falls one standard deviation above the mean, which places it in the High Average range (approximately the 84th percentile). This indicates above-average general intellectual functioning. - Reading – 98th Percentile: Very High
Percentile ranks compare an individual’s performance to others in the same group. The 98th percentile means Beyoncé scored higher than 98% of her peers. This places her in the Very High range for reading ability, demonstrating exceptional literacy skills. - Math – 44th Percentile: Low Average
A percentile of 44 means the individual performed better than 44% of peers. This falls within the Low Average range, which is typically considered from the 25th to the 50th percentile. This suggests Beyoncé’s math performance is somewhat below average relative to her peers, though not significantly impaired. - Self-Efficacy – T = 71: Very High
T-scores have a mean of 50 and a standard deviation of 10. A score of 71 is over two standard deviations above the mean, which places it in the Very High range. This indicates that Beyoncé has a strong belief in her ability to succeed and manage challenges, which can positively influence her performance and motivation.
Summary:
The accurate descriptors for Beyoncé’s test results are:
- IQ: High Average
- Reading: Very High
- Math: Low Average
- Self-Efficacy: Very High
This profile highlights strengths in verbal and emotional domains, with relative weakness in math.
