Kali decided to keep a log of how much money she spent on lunch at school each day for three weeks. Her data included the following numbers:
Week 1: $2.50, $3.00, $2.75, $3.00, $2.50
Week 2: $3.00, $2.50, $2.75, $2.50, $3.00
Week 3: $2.50, $2.75, $2.50, $3.00, $2.50
What is the mode of this data?

What is the mode of this data?
In order to find mode, we must determine which number occurs most often in the data set. In this particular set, $
occurs 
times, $
occurs 
times, and $
occurs 
times. Since $
occurs the most often, it is the mode for this set of data.

Which measure of central tendency would you use to find the term that is most occuring?
Which measure of central tendency would you use to find the term that is most occuring?
Mode is the number that occurs most often, so that is the correct answer. Median is the middle number, while mean is the average of the set. Range is the difference between the greatest and least numbers.

Consider the data set
Which of the following elements replaces the box to make 30 the mode of the data set?
Regardless of what value replaces the box, 40 will still be the most frequently appearing element in the set (four times, more than any other element) - that is, 40 will be the mode.

Arrange the elements in ascending order.
The mode of the set is the element that appears most frequently, which here is 15.
The median of the set is the element that appears in the middle, which here is 19.
(B) is greater.
