Here are the ages of Jahna and her cousins: $11,6,8,4,3,13,$ and $4$.

1. Find the mean, median, and mode of their ages.

   Hint 1(a):

   For help with mean, median, and mode, refer to the Math Notes box in Lesson 1.3.3.

   Hint 2(a):

   Be sure to put the ages in numerical order (from least to greatest). It will definitely help you when looking at this data!

   Answer (a):

   In this set of data, the mean is $7$, the median is $6$, and the mode is $13$.

2. Create two different histograms to represent this data. One of them should have data in two columns, and one should have data in three columns.

   Hint 1(b):

   For help with histograms, refer to the Math Notes box in Lesson 1.1.1.

   Hint 2(b):

   For both histograms, it will be best to label the horizontal axes ''Age'' and the vertical axes ''Frequency.''
