Lab 2 2 Lab 2 There are five basic types of graphs. They are all different, but all are used to organize and simplify data. Graphs, when used accurately, can be impactful and extremely helpful. All graphs need to use correct and appropriate scales, labels, titles, and a legend with all that they can then help us to make sense of data. 1) A bar graph uses either vertical or horizontal bars to display data and is useful for comparing and organizing data. Normally, things like the least, greatest, range, mode, etc. can be found using the graph. (5.5, 2012) 2) A line graph uses plotted points to represent numbers pulled from data and is useful for showing changes in data over a period of time and showing trends. (5.5, 2012) 3) A line plot organizes data by plotting x’s on a number line and is used for data analysis, studying data, and making observations. Range, least, greatest, and mode can usually be easily found on the line plot. (5.5, 2012) 4) A pie chart compares numbers in a set of data by showing the relative sizes of parts that make up a whole. This is done by sectioning parts of the whole and can clearly demonstrate the least and greatest. (5.5, 2012) 5) In stem and leaf plot the data are organized from least to greatest. Then the digits of the least place value (like the ones place) form the leaves and the next place value digits (like the tens) form the stems. This graph is useful for analyzing data because it shows all the

###### "Before using Course Hero my grade was at 78%. By the end of the semester my grade was at 90%. I could not have done it without all the class material I found."

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
