Let’s start with calculating mean, SD and CV for glucose IQC Level 1 # Some arbitrary glucose IQC results --> Level 1 glucose_L1 <- c(101, 111, 103, 98, 100, 106, 103, 94, 90, 102, 98, 100, 97, 107, 98, 106, 107, 87, 100, 107) # We are creating variable named "glucose_mean_L1" and assigning calculated mean to this variable glucose_L1_mean <- mean(glucose_L1) #print Mean glucose_L1_mean ## [1] 100.75 # We are creating variable named "glucos_sd_L1" and assigning calculated SD to this variable glucos_L1_sd <- sd(glucose_L1) #print SD glucos_L1_sd ## [1] 5.
