A school psychologist was asked to assess a group of 17 students who failed their math exam. She screened for possible learning disabilities and wanted to check their global IQ scores. Each student was asked to complete a global IQ test. After conducting a correlation, she found that there was a strong positive correlation with r= 0.79 between IQ and math exam scores which was found to significant at p < 0.05. Based on the correlation, IQ was found to explain 61% of the variability in the student's math exam scores. After conducting the correlation, the teacher took another random group of 18 students who scored well in their math exam. She created two groups based on math exam scores (Group 1 high exam scores Vs Group 2 failed exam scores). The psychologist hypothesises that the students in the failed exam score group will have lower global IQs than students in the high exam score group who were used as a control group. A trial was conducted to assess the impact of IQ on math scores.…
