Hello, my name is Walter Unglaub, and this is how to graph a table of values. So let's say that we're given a table of values, in this case data about two different countries in which we examine the population of each of the countries in millions over a span of time. So our x axis data will be time, say in years, where I have year one, year two, year three and year four. And then my second column for this table of data will be the population in millions of country one. So I'm gonna denote that as p sub one. And let's say I have one million people the first year, and the second year I have two million people, and the third year I have three million people, and then finally let's say I have five million people the fourth year. So, I can also have another column, a third column to tabulate the data of population for a second country, which I'll denote by p sub two, and here let's say I have for year one two million, and this stays constant for all time, for whatever reason. We can take this table of data and we can plot it. So, along the x axis I'll have time, and I just have to put down the different data points. So for population one, at year one, I have one million, and then I have two million at year two. At year three I have three million and then finally at year four it jumps up to five million. So here I would simply connect the data points, and then I could try to perform some sort of fit on this data. Four population two, the population in millions of country number two, for all time I simply have data points set at two million. And here I connect them and they form a straight line. So, in this plot then, right here, I have plotted two sets of data representing the populations of country one and country two in millions over time, and then I can do statistical measures or other analysis on this data as I see fit. My name is Walter Unglaub, and this is how to graph a table of values.
