Research has shown that there are persistent differences in IQ test scores across different racial and ethnic groups in the US, with some groups consistently scoring higher or lower on average than others. However, it is important to note that while there may be differences in average scores, individual differences within each group are greater than differences between groups.
To find the median of Wednesday's test scores, first arrange the scores in numerical order from least to greatest, then select the middle value as the median. If there is an even number of scores, the median is the average of the two middle values.

One hypothesis could be that studying with music may either positively or negatively impact student test scores. For example, listening to music could improve focus and help some students retain information better, leading to higher scores. On the other hand, music might be a distraction for some students, hindering their ability to concentrate and negatively impacting their test performance.
IQ scores can be influenced by a variety of factors, including cultural bias in test design, access to education, and socio-economic background. It is important to recognize that intelligence is complex and cannot be solely determined by race or culture. Differences in IQ scores among racial or cultural groups are often due to social and environmental factors rather than inherent differences in intelligence.

You should think of a dependent t as being a single-sample t on the difference scores. This gives it 1 less than the number of differences as the df. Say you have before/after scores for 10 people. You have 20 scores, but the test is done on the differences, of which you have 10 and that means 9 df. You typically obtain df from n - 1, as you do in this case, you just need to be careful to think of this as the number of pairs and not scores.
