The following is a list of Levels of Service Inventory (LSI) scores taken from a sample of 10 inmates on their first day of incarceration at a county correctional facility. The LSI is a measure of inmate security risk; the higher the score, the greater the risk: 2, 8, 5, 7, 5, 9, 4, 8, 4, 8. Find the mean, median, mode, range, and standard deviation.
