Open this file for the notes for this lesson and then save the file on your laptop.

After going through the notes, attempt these questions.

1. Complete this table and then determine the range and mode for this set of data.
 * = Outcome ||= Freq. ||= c.f. ||
 * = 5 ||= 1 ||=  ||
 * = 6 ||= 4 ||=  ||
 * = 7 ||= 6 ||=  ||
 * = 8 ||= 7 ||=  ||
 * = 9 ||= 5 ||=  ||
 * = 10 ||= 2 ||=  ||

2. Create a table of data for the cumulative frequency histogram shown below. 

Determine the range, mode and median for this set of data.

3. Use the cumulative frequency graph below to determine the range, mode and median.

Now try the activity from the website below. [|Median, Mode, Mean & Range]

Here are some extension questions for fast finishers.

4. This frequency polygon represents a survey conducted of all families in Bridge Street.  a) Using this data, complete a table with headings Number of Children, Frequency and Cumulative Frequency. <span style="color: #008000; display: block; font-family: 'Comic Sans MS',cursive; font-size: 150%; text-align: left;">b) How many families were surveyed in Bridge Street? <span style="color: #008000; display: block; font-family: 'Comic Sans MS',cursive; font-size: 150%; text-align: left;">c) How many children live in Bridge Street? <span style="color: #008000; display: block; font-family: 'Comic Sans MS',cursive; font-size: 150%; text-align: left;">d) What was the most common number of children per family (mode)?

<span style="color: #000080; display: block; font-family: 'Comic Sans MS',cursive; font-size: 150%; text-align: left;">5. Add a cumulative frequency column to the tables below in order to calculate the median in each case. <span style="display: block; font-family: 'Comic Sans MS',cursive; font-size: 150%; text-align: center;"> <span style="display: block; font-family: 'Comic Sans MS',cursive; font-size: 150%; text-align: center;">
