MATH 110 Chapter Notes - Chapter 1: Bar Chart, Histogram, Arrow Keys
Document Summary
Histogram is the most common graph of the distribution of one quantitative variable. Although histograms resemble bar graphs, their details and uses are different. Histogram: horizontal axis is marked by unit of measurement for the variable. Bar graph: horizontal axis simply identifies the quantities being compared. Step 1: e(cid:374)te(cid:396) the data i(cid:374)to a list. P(cid:396)ess the tat (cid:271)utto(cid:374) a(cid:374)d the(cid:374) p(cid:396)ess enter fo(cid:396) the (cid:862)edit(cid:863) optio(cid:374). Enter the first number, and then press enter. Continue entering numbers, pressing the enter button after each entry. Step 2: p(cid:396)ess (cid:862)(cid:1006)(cid:374)d,(cid:863) the(cid:374) (cid:862)y=(cid:863) to (cid:272)hoose (cid:862) tat plot. (cid:863) Step 3: p(cid:396)ess enter to (cid:272)hoose plot (cid:862)(cid:1005). (cid:863) Step 5: press the down arrow key (the arrow keys are at the top right), then press the right arrow key twice. Your cursor should be flashing over the histogram option, which is the top right option in the list.
