To make a tally chart, single lines are drawn next to one another until reaching five, where the fifth line crosses the four other lines diagonally. This is a simple charting method that can be used quickly for surveys or other needs.
Continue ReadingA tally chart works by grouping tallies into fives. For instance, if taking a poll on people's favorite colors, after the color name, a person would add the tallies one by one. Once the person taking the survey reaches four, the fifth answer becomes a diagonal tally that crosses the other four. That groups the section into five, allowing them to quickly be added by fives as the number of answers increases.
There is actually another kind of tallying called Tukey tallying, according to Math Is Fun. This type of tallying uses four dots to create a square, then lines are drawn between each dot. Dots are used for tallying one through four, then each line represents five, six, seven, eight, nine and ten. When ten is reached, the image looks like a square with four dotted corners and an X through the middle.
Tukey tallying allows surveys to be taken and scored in groups of ten instead of five, so this can be helpful for questionnaires with a high number of answers.

Full Answer >Vertices are the points, or corners, in geometrical and mathematical shapes where two or more lines meet but do not cross, according to Math Open Reference. Vertices can exist in two-dimensional and three-dimensional shapes. The singular form of vertices is vertex. Sometimes, the term vertex is also used to describe certain points on quadratic equations.
Full Answer >Parallel lines are lines that never cross each other. The key to constructing parallel lines is to know that they have the exact same slope.
Full Answer >To make a pie chart, organize the data as fractions of the whole. Multiply each fraction by 360 degrees, which is the number of degrees in a circle, and assign each multiplied fraction a portion of the pie chart.
