Week 1 Assignment

The chart of graph selected comes from the US Centers for Disease Control and Preventions MMWR in the article, "Heat Illness Among High School Athletes --- United States, 2005--2009"

Identify the type of chart or graph and what this type of chart or graph usually depicts.

At the bottom of the article, there is a verticle bar chart of the Number of time-loss heat illnesses among high school athletes, by month. verticle bar charts usually depict the number of events or occurrences by group (in this case the number of time-loss heat illnesses by month). Sometimes bar charts are also used to depict percentages by groups as well.

Why was this graph chosen to display this data?

The graph shows a striking spike in the number of heat illnesses in the Month of August -- one of the warmer months and first months in which football training occurs. It speaks to one of the main points of the article -- that heat illnesses occur most frequently when athletes have not yet had a chance to become acclimated to the heat.

What other types of graphs could have been used? Why?

A horizontal bar chart could have been used as this is the same chart as the one presented only the axes are interchanged. In addition a line graph could have represented the same information to show the trends in illnesses over time.

Is the scope and scale of the graph appropriate? Why or why not?

Yes, the scope and scale of the graph are appropriate. The x-axis of the chart shows all the available months of the study, with the exception of 17 cases in which there was missing data, but this is noted in the title above the graph. Since the graph consists of counts, the y-axis is appropriately shown from 0 to 70, just under the maximum number of cases in any...

REFLECTION
The first thing that puffs in my mind when I heard the word STATISTIC is that it was a very hard subject because it is another branch of mathematics that will make my head or brain bleed of thinking of how I will handle it. I have learned that statistic is a branch of mathematics concerned with the study of information that is expressed in numbers, for example information about the number of times...

Uses of Statistics
The use of statistics has been proven to assist the understanding of information, data, in many ways. Statistical information is not just collected, but it is also organized and quantified, providing a clearer picture for further study. This writer will explain how statistics are used in my personal workplace, and...

...REFLECTION ON MEANING, USE AND HISTORY OF STATISTICSStatistics even before came out of the daily needs of the people. From what I thought simple now and complicated in the past, statistics remained a great help to all of them. I imagined how the life would be if I were to live during the time of De Moivre, Adolf Quetelet, Sir Francis Galton and among others. I would be amazed by their works and start to love mathematics. I’d be...

Chart/Graph Paper
“Data are summarized in a visual way using charts and graphs (Rumsey, 2010).” Some of the basic graphs used include pie charts, bar charts, and histograms. Pie charts used more for percentages, bar charts used to compare groups and histograms to show numerical data.
Pie charts take data that is...

...Charts and graph are images that present data symbolically. They are used to present information and numerical data in a simple, compact format. This paper will focus on three types of charts and/or graphs which are: pie charts, bar graphs, and histograms.
What types of data there are and how the data was collected is important for the reader to understand.. According to Bennett, Briggs, and Triola (2003) there are two types of data. They are:...

...Statistics is the study of the collection, organization, analysis, interpretation, and presentation of data.[1][2] It deals with all aspects of this, including the planning of data collection in terms of the design of surveys and experiments.
In mathematics, a graph is a representation of a set of objects where some pairs of the objects are connected by links. The interconnected objects are represented by mathematical abstractions called vertices, and the links...
