# Functional Skills: Data Tables

## Functional Skills: Data Tables Revision

**Data Tables**

**Tables** are ways of displaying data in a clear way. The information will be shown in **rows **(across) and **columns **(down). There are many different types of table that you will see in mathematics, but here we will just look at a few.

**Mileage Charts**

**Mileage charts** are one type of table. They tell you distances between different places. There are a couple of different styles of mileage charts that you may see.

**Example:** Use the **mileage chart** to find the distance between **Manchester** and **York**.

**Step 1:** Move down the column from the ‘**Manchester**‘ heading and across the row from the ‘**York**‘ heading.

**Step 2:** Where the row and column meet is the distance between the two places.

So, the distance between **Manchester** and **York** is 67 miles.

You may also see the data displayed in a **mileage chart** such as this:

The red arrows and blue arrows give the same result for the distance between **Manchester** and **York**, 67 miles.

**Tally Charts and Frequency Tables**

**Tally charts** and **frequency tables** allow you to put data into different categories. Each row will show you how much is in each category.

e.g. this tally chart shows types of sandwiches left in a cafÃ©.

There are 3 ham sandwiches, 1 cheese sandwich, 4 chicken sandwiches, 6 egg sandwiches and 1 beef sandwich left.

You can add a frequency column to the tally chart. Each row in the frequency column represents the total number of tally marks in each row.

**Making Data Tables**

A question may require you to **create your own data table**. There is no right or wrong way to do this, it just depends on what data the table is needed for.

You will need to make sure that the table has enough rows and columns to fit in all of the data.

**Example:** Jordan is planning on ordering a group takeaway for her and her 6 friends. To make things easier she decides that people can order either a pizza, a burger or a kebab.

**Design a table** to show each persons order and the total number of people that chose each option.

This table could look like this (remember there is no correct way!):

## Functional Skills: Data Tables Example Questions

**Question 1:** Use the mileage chart below to answer the following questions.

All distances are shown in miles.

**a)** What is the distance between Hull and Manchester?

**b)** Frankie drives from Manchester to Lincoln and then to Hull. What is the total mileage for her journey?

**[3 marks]**

**a)** Going across from Manchester and down from Hull, until they meet, gives a distance of 98 miles.

**b)** Going across from Manchester and down from Lincoln, until they meet, gives a distance of 83 miles.

Going across from Lincoln and down from Hull, until they meet, gives a distance of 48 miles.

Therefore, the total distance travelled by Frankie is

83 + 48 = 131 miles

**Question 2:** The tally chart below shows peoples’ favourite colour.

Use this table to answer the following questions.

**a)** How many people said that yellow was their favourite colour?

**b)** How many people were asked in total?

**[3 marks]**

**a)** There is a group of 5 lines and 2 extra lines, so the total is 5+2=7

**b)** Total = 4+1+4+7+2=18 people

**Question 3:** Jamie is a builder, he needs to order some materials from his supplier.

Design a table that Jamie could use to record the details of his order.

The table needs to include the items he needs to order, the number of each item and the price of each item.

It needs to include the total cost of the order also.

Design a table that Jamie could use.

**[2 marks]**

You could create a table of any style (there is no wrong or right way), as long as there is enough space for the information.

Here is an example:
