Answer:
mean is the average of all the values:
( 15.07 + 15.47 + 15.93 + 15.86 + 15.07 ) / 5 = 15.48g
median is the middle value AFTER it has been arranged in increasing order:
the increasing order is: 15.07, 15.07, 15.47, 15.86, 15.93
the middle value is 15.47g making it the median.
the mode is the most repeated value: 15.07g
