# What is the correlation between the boys English MCAS scores and their attendance (grades 4-5)?

Using the NoNameSchoolData, answer the following questions:1.    What is the average English MCAS scaled score for girls in grades 4-5?2.    What is the standard deviation?3.    What scaled score is 1 standard deviation below the mean for these students? Students who score at this level are in what percentile for their group?4.    What scaled score is 1 standard deviation above the mean for these students? Students who score at this level are in what percentile for their group?5.    Taking the answers to #3 and 4, what percent of students have a score between these 2 limits?6.    Repeat questions 1-5 for boys in grades 4-5.7.    Which cohort (boys or girls) had the highest mean English MCAS score? Is the difference significant (p < .05)?8.    What is the correlation between the boys English MCAS scores and their behavior (grades 4-5)?9.    What is the correlation between the boys English MCAS scores and their attendance (grades 4-5)?10.    Describe the relationship between race and English MCAS performance levels in grade 4-5.11.    Based on what you found in #10, write a hypothesis which offers an explanation for the results and might be tested with data found in this spreadsheet. Test
your hypothesis; what is the result?
