Which student is more precise and which student is more accurate?

Five students performed a lab experiment on volume measurements. Here are the results after 5 trials Luke: 23.5 mL: 23.8 mL240 ml, 23.3 ml, 23.5 ml Sharon 23.7 ml: 23.7 ml, 23.7 ml: 23.9 ml, 23.7 ml Bridgit 222 mL, 22.8 ml, 23.1 ml, 23.0 ml 22.9 ml. John: 23.7 ml, 23.6 ml, 23.6 ml, 23.7 ml, 23.3 ml Gabby 21.9 ml, 22 8 ml, 23.4 ml 23.1 ml 27 1 ml Knowing that the true value is 23.0 mL one can say that the more accurate among these students is and the more precise is
