Gathering data requires an organized system of collecting the information. Using tally marks is a simple
way for you to keep track of information as you collect it. Tally marks are most effective when recorded in
an organized column chart like the one below. Grouping the tally marks in 5s makes it easier for you to total
the numbers in each category by skip counting. Remember to keep your bundles of 5 separate from each other.
Tally charts should always be given a title to inform the reader about the meaning of the data.

Another useful tool for organizing data is the line plot.

The line plot displays each piece of data by marking an ‘X’ (cross) above the corresponding choice/value
along a horizontal line, as shown in the following examples.

*Example:*

In the line plot below:
