Petal Length (cm)
Image from Wikipedia
This histogram shows the petal length of an Iris. As you can see, there is no clear mean, however, an approximate mean can be
determined by using the class intervals and multiplying by the frequency, then divide by the total number.
The estimated mean using the middle of the class interval (add .25 to lowest number of the interval) Please help!!!
