A bar graph is used to compare items between different groups and track changes over a period of time. Bar graphs are best used for changes that happen over a large amount of time instead of just months or weeks.
Know MoreBar graphs feature rectangular bars with lengths that are directly proportional to the values they represent. A bar graph can be plotted both vertically, which is sometimes referred to as a column bar graph, or horizontally. Bar charts also resemble histograms, which can display a record of continuous data, but the main difference is the type of data that is represented in the two.
Learn MoreIn the branch of mathematics known as set theory, roster form is when a group of set members is placed between brackets, with the individual elements separated by commas. For instance, {2, 4, 6, 8} is the proper form for the roster of even numerals between 0 and 10.
Full Answer >An ogive graph is a smooth S-shaped curve that is used in statistics. The graph is obtained by plotting the values of cumulative frequency against the upper boundary points of the class intervals.
Full Answer >Read a crane load chart by first looking at the top axis. The first number on the top axis is the gross vehicle weight. In the other two columns, you will find arrows that indicate the weight load for each axle,which depends on what additional accessories are loaded. Use this information to determine lift capacity, lift range, lift angle and crane in motion weight limits.
Full Answer >A cumulative frequency polygon is a plot of the cumulative frequency against the upper class boundary with the points joined by a line segment. An ogive is any continuous cumulative frequency curve, including cumulative frequency polygons. A cumulative frequency polygon displays cumulative frequency on the x-axis and class marks on the y-axis.
