Background: You just finished teaching your first PSYCH 248 lab section, and it's time to calculate the grades. Your wonderful teaching assistant created an Excel file with all of the students' exam grades, homework grade, and lab grade as well as their gender. Your next steps are to calculate each student's final grade, convert those scores to letter grades, and describe the distribution of scores. Data Management Steps: 1. Download the CA1_Dataset.csv file from Blackboard. 2. In Excel, calculate the final Number Grade, Letter Grade, and Z-score for each student. a. To calculate the Number Grade, type a numerical equation after an = sign in a cell or use the =AVERAGE() formula; however, keep in mind that the =AVERAGE() formula will always give you the regular mean, not the weighted mean. Grades for this course are comprised of three parts: lecture exams (60%), homework (20%), and lab (20%). b. To calculate the Letter Grade, use the =IF() formula with a series of logic statements or enter the data by hand. For this assignment, let's convert Number Grade into Letter Grade using the following rubric: A (90-100), B (80-89), C (70- 79), D (60-69), F (
