3.6 Tables
In a table, we structure and order facts so that they are easier to read and understand what is presented.

Imagine that you got the information presented for you like this:

The number of students in class 8A which have gotten different grades in Swedish, English, Biology and History looks like the following:

Swedish: 12 G, 7 VG, 3 MVG i 2 IG.
English: 9G, 11 VG, 3 MVG i 1 IG.
Biology: 8 G, 7 VG, 5 MVG i 4 IG.
History: 10 G, 9 VG, 4 MVG i 1 IG.

or like this:

Isn’t it good to use tables?

A table consists of columns and rows which have clear headings.
Units can be written either in the tables or in a table key.

Are written over the table itself.  Here is also written an explanatory text about what the table contains.  If the values’s units are not written in the table, it is written here, for example that “all values expressed in %”.

Frequency Table
By frequency, we mean occurring, in other words how much or often something occurs.  This occurance can be summarized in a table.  This table is called a frequency table.

Here is an example:

In class 7D, the students were asked in which month they were born.  The teacher then wrote every student’s birth month on the board:

 March August May July April March March February December September April January June July August January June April October August September May July May October March March February

Then the teacher summarized the results in the form of a frequency table.

By frequency, we mean the number of time every month occurs.  The relative frequency is calculated by dividing the frequency (part) by the total number of students (proportion).  In this study, we can then see that for example 17.9 % of the students in class 7D are born during the month of March.
