Final answer:
The study from De Anza College investigated the relationship between student anxiety levels and need for success in school, determining whether these are independent through analyzing a sample of 400 students. calculations such as the expected number of students with both high anxiety and need to succeed in school (approximately 22) provide insights into potential patterns or relationships. Additional variables, however, must be considered for accurate interpretation of these implications.
Step-by-step explanation:
Many students have had the unpleasant experience of panicking on a test because the first question was exceptionally difficult, leading to what is known as "debilitating anxiety". A study at De Anza College examined whether the level of anxiety a student experiences is related to their need to be successful in school, and whether these two factors are independent events. To determine this, they collected data from a sample of 400 students.The expected number of students with both a high anxiety level and a high need to succeed can be calculated using probabilities. If anxiety and the need to succeed are independent, the expected number across different anxiety levels and success needs can be determined by the formula (row total) x (column total) / total surveyed. For instance, the expected number of students who have a high anxiety level and a high need to succeed in school is approximately 22.
This demonstrates that there might be a relationship or pattern between anxiety levels and the drive for academic success. It's important to note that without additional context or results from the actual observed data, we cannot definitively determine the implications of these scores. Other lurking variables could also play a role and should be considered when evaluating the association between these two variables.
