Thank you for the opportunity to help you with your question!

According to given question

Mean=sum of all data /number of data

=11+11+12+12+12+12+!3+15+17+21+21+21/12

Mean=178/12=14.33

median=middle value of data

median=12

Mode=It is the value of set that occurs most offen

Mode=12

Mean is greater from mode and median
