Statistics and graphs go hand in hand, with graphs being one of the most effective ways to clearly display statistical information, so you can use statistics homework help to learn how to create them correctly and effectively. Although there are many different types of graphs, each with its own uses and purposes, all of them share some common traits as well. You’ll want to read on if you’re looking for the best way to graph your data, but first let’s take a look at the basic definitions of each type of graph that you might encounter.
Bar Graphs
A bar graph is a visual representation of information that uses either bars or columns to show comparisons between values. Bar graphs use height, length, or area to show the magnitude of the information being represented. The most common type of bar graph is the horizontal bar graph, where the bars are laid out from left-to-right horizontally. There are many benefits to using bar graphs in statistics homework help as they allow you to compare different things at once and add in additional information such as a legend and axis labels. One downside is that it may be more difficult for people with reading difficulties to understand them when compared to other types of graphs.
Line Graphs
Line graphs are one type of graph that you can use in statistics homework help. This type is the most common and easiest to read. They show the relationship between two sets of data that vary over time or represent changes in a single set of data over time.
Line graphs are very easy to read, unlike other types such as pie charts, which can be difficult to interpret without some knowledge on how they work. Line graphs also typically include an X-axis that represents time and a Y-axis which represents values or changes over time.
Line graphs are best when comparing two sets of data such as percentages or measurements since they show the actual relationships between both sets.
Circle Graphs
Circle graphs are a simple way to display data. They are one type of graph that you can use when doing statistics homework help. In order to create a circle graph, you need to know the data points and the number of units for each point. The circles should have an even distribution on either side of the circumference. For example, if the diameter is 5 cm then divide it in half so that there is 2 cm left over from each side.
Histograms
One type of graph you can use to represent data is a histogram. Histograms are similar to bar graphs, except that the bars are not horizontal, but are vertical instead. A histogram is used when data has a limited range or if there is no order in the data and it cannot be represented as a line graph. Histograms may also be used to show changes over time in a process by graphing the number or percentage of occurrences at different intervals. Each interval on a histogram represents one or more occurrences and its height corresponds to the number of occurrences within that interval.
Scatter plots
Scatter plots are a type of graph that shows how two variables are related. In this case, the scatterplot displays how the income and education levels in a city are related. The graph displays points with one dot being low income and low education, two dots being medium income and medium education, three dots being high income and high education, four dots being low income and high education, five dots being medium income and low education, six dots being medium income and high education, seven dots being high income but no data about their level of education.
A picture speaks a thousand words so let's talk about what this scatter plot is telling us.
