The data set I decided to explore was the U.S Population data set that shows the overall United States population from 1790-2010 in each decennial census.<\/p>\n

The data set was very sparse, containing only two columns. One column was the\u00a0year the census was obtained while\u00a0the other column was\u00a0the recorded population. Each record was the population of the US per a given year. Since the data was so simple, I decided to use a line graph\u00a0to visually represent the trend of population growth in the United States. A line graph was the best option for this data set as it represents change in data over time (change in population as year increases). Both the variables were quantitative, continuos\u00a0data which also made a line graph ideal as it shows continuos trends efficiently. The year was plotted on the x axis and the population was plotted on the y because the population is dependent on the year recorded. I used Plot.ly to create this graph as it was very straightforward and easy to embed in the post.<\/p>\n

The important thing that the graph shows is the rapid population growth that starts after the 1800’s. While you can see the growth in population from the data set as well, the graph gives viewers a quick and more impactful perspective. The concave up shape of the graph signifies a major growth trend in a visual manner that the records do not easily convey. Not only does it show the rapid growth beginning from the 1800’s, but one can infer from the graph that the U.S population is just going to continue to grow, as the line continues to rise steadily. Further research about population growth can be done simply by looking at this graph. For example, one can look into the events that happened in the mid 1800’s that would have caused a spike in population growth (e.g the Industrial Revolution creating more resources for population growth). It is also easy to add data to the records every decennial year and continue the line chart to see if the population is still growing rapidly or leveling out.\u00a0If one didn’t have the graph to look at, it would be more difficult to interpret trends from the data because it is not as straightforward and intuitive to the eye when purely looking at numbers. Graphs are highly efficient when working with and presenting large numbers because they are less strenuous to look at and catch the\u00a0viewers attention faster.<\/p>\n","protected":false},"excerpt":{"rendered":"
