The stem is the left hand column which contains the tens of the digit  and the leaf is the right hand column showing all the ones digit for each of the tens digit on the left hand side.

Here we have to determine the mean ,median,mode and range of the stem and leaf plot.

From the stem and leaf plot the data are

{41,42,44,44,52,54,61,63,64,67,67,67,67,68,68,72,72,73,80,81,82,84,85,86}

So the mean will be the sum of all data divided with the total data

Sum=1584

Total data=24

Median=Middle value of the data,As the total data is even therefore ,Median =12th value+13th value/2 =(67+67)/2 =67(answer)

Mode=>The data that occur most of the time.Her 67 occur 4 time which is maximum.

Range:-Difference between the maximum value-Minimum value =86-41=45(answer)
