Tables - Cycle 2

A table of values is a tool used to organize and present the results of a survey.

Horizontal table of values

Vertical table of values

The title indicates that this table represents the number of candles that Jalil sold to fundraise for her soccer team.

This table shows the number of vanilla, cinnamon, citrus and mint scented candles sold by Jalil.

The data in this table are represented by tally marks.

There are 8 tally marks under the Vanilla category. This shows that Jalil sold 8 vanilla candles.

This table shows that Jalil sold 8 vanilla candles, 4 cinnamon candles, 11 citrus candles and 6 mint candles.

Some tables may have a legend. Look at the value associated with each symbol in the legend to know what they represent.

Example:

The legend shows that one dot represents 1 bracelet and that one X represents 5.

What is the most popular hobby among the students in Ms. Caroline’s class?

I count the X’s or I look at the totals in each category to know which hobby is the most popular. In this table, I see that the category containing the most data is the one with 11 X’s.
I look at the category associated with this number. The category containing 11 X’s is Reading.

The most popular hobby in Ms. Caroline’s class is Reading.

How many students are there in Ms. Caroline’s class?

I look at the totals in each category. The totals indicate that 7 students prefer video games, 11 students prefer reading, 4 students prefer drawing and 3 students prefer other hobbies.
Next, I add up the total number of students in each category.	7 + 11 + 4 + 3 = 25

There are a total of 25 students in Ms. Caroline’s class.

A double entry table is a tool used to organize and present the results of a survey with 2 questions.

Marie asks the students in her class to answer the 2 following questions:

1. What is your favourite animal between cats, dogs, fish or birds?
2. What is your favourite colour between blue, red, green or orange?

All the possible choices are shown in the double entry table below.

Julien's favourite animal is dogs and his favourite colour is green.

Identify the box that corresponds to Julien's choices in the double entry table below.

I analyze Julien's answer to the 1st question. Julien answered that his favourite animal is dogs. So I turn my attention to the 2nd row of the table, since it represents dogs.
Now I analyze Julien's answer to the 2nd question. Julien answered that his preferred colour is green. I turn my attention to the 3rd column of the table, since it represents the colour green.
I find the box that is at the point where the row and column meet.

The box in the double entry table that corresponds to Julien's 2 choices is therefore the one that contains a green dog.
