Dot plots display data in a way that makes it easier to identify the median of a set of data. This knowledge of median is the foundation for understanding interquartile ranges.
What to look forStudents should note that there are the same number of points to the left and to the right of the median; regardless of the shape of the distribution.
Identify the following as true or false.
a. The median is the midpoint between the smallest and largest values in the data set.
b. At most half of the values in a data set have values less than the median.
c. If you add 10 to every element of a data set, the median will not change.
d. If you add 10 to every element of a data set, the IQR will not change.
