Wang Gang's test scores in eight units of mathematics this semester are as follows: 88, 87, 9 1, 89, 94, 85, 98, 100( 1). The average value of this set of data is _ _ _ _.
( 1)(88+87+9 1+89+94+85+98+ 100)÷8,

=732÷8,

=9 1.5;

(2) The given data are arranged in descending order: 85, 87, 88, 89, 9 1, 94, 98,100;

The median is (89+9 1)÷2=90,

(3) The statistical chart is as follows:
