Line charts, or line graphs, are powerful visual tools that illustrate trends in data over a period of time or a particular correlation. For example, one axis of the graph might represent a variable value, while the other axis often displays a timeline.
Each value is plotted on the chart, then the points are connected to display a trend over the compared time span. Multiple trends can be compared by plotting lines of various colors or patterns.
For example, the popularity of various social-media networks over the course of a year can be visually compared with ease through the use of a line graph. Simply plot each company’s user base for each month of the 12-month span, then connect the dots with a line of a designated color. Audiences will quickly recognize which social networks are the most and least successful, as well as which are experiencing growth or loss.

I chose to look for research studies relating to MS (Multiple Sclerosis). I was actually diagnosed with MS, a couple of weeks ago and have been reading a lot about it.
On the link below, there are charts that you can drill down on to display all kinds of information about MS relating to a region in the world, and information about percentages of symptoms, and some limited information about testing to find the diagnosis. It is noted that each country in the world, that is represented in this study, has a designated person who collects the data from physicians and other sources.
The maps that show the percentages of visual disturbances as a form of diagnosis (which is what the link was for) was of special interest to me, as that is what prompted me to finally go to the doctor- when I lost the peripheral vision in my left eye. I have had other symptoms, but I brushed them off as just random things.
I believe this is an example of inferential statistics because they do not provide the mean, or standard deviation- so this seems to me more of sampling information.

Many times in my Military career I always used the saying “Death by Power point”, towards the end of my career I developed and set through weekly briefings that used graphs or charts. Since being out I now understand why senior leaders conduct weekly meetings and love their graphs or charts. As many people know leaders tend to not have a lot of time or attention span to truly grasp what is going on within their organization and this is why graphs or charts is vital for grabbing their attention for a short period of time. This is why for this week I stayed with a Military theme and used the Veteran population study. In this study they use three main graphs that help the reader to understand the concept the Veterans Affairs department was trying to convey.
The first figure shows how the next 30 years veteran’s ages will become more evenly distributed. The lines represent the years starting with 2015 and each time increasing by 10 years. It displays by the thousands on the y and the age on the x. The second figure displays the percentage of veteran’s genders in the next 30 years. The bars represent males (as blue) and females (as red). It displays by the millions on the y and years starting with 2015 on the x. The third figure projects what departments will be affected and benefit from this research study. This graph shows the data sources being gathered by the analysis, then they develop the model, and all the smaller circles are the organizations within the Veterans Affairs that will receive the model.
