Answer:
1st Qtrl: 11
Median: 20.5
3rd Qtrl: 25.5
Range: 22
Step-by-step explanation:
Median = average of 2 middle values (18 + 23) / 2
1st Qtrl = average of 10 and 12 (the lower half of data)
3rd Qtrl = average of 25 and 26 (the upper half of data)
Range = largest value - smallest value; 30 - 8 = 22
