To find the mode of the given data first we have to arrange it in a increasing order then find out mean and median of the given data
0.7,1.7,3,3.2,4.1,5.9,6.6,8.9 is in increasing order
For finding the median we need to take the average of 4th and 5th terms because we have the no of terms in the sequence is even not odd so we need to take the average the 4th term=3.2 and the 5th term =4.1
