“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 categorized and shows percentages or individuals that can be placed into each category. The sum of all pie slices should equal 100 or 100%. Pie charts are in a circular shape which allows slices of the “pie” to be compared easily. An example of a pie chart would be showing where your money goes when you purchase a lottery ticket. A designated amount for prizes, retailers, and the lottery commission itself, and education.

Bar graphs are used also in summarizing data which has been or can be categorized. The bar graph breaks data into groups showing how many pieces are in one group, or what percentage. Bar graphs are often used to compare groups and breaking the groups down and showing the information side by side. An example of a bar graph would be the number of women in the workforce. Breaking that up into number with children, with children under 10 and children 11-17. Units should be evenly spaced when using a bar graph, beware of the scale used and ensure accuracy when plotting graph points, and if bar graphs represent percent’s be sure to include the total number of individuals or items used to obtain the percent’s Histograms are the graph of choice for numerical data. “Histograms provide a quick look at all the data broken down into numerically ordered groups (Rumsey, 2010)”. A histogram is a bar graph that applies to numerical data. Categories in a histogram are ordered small to large. The bars on the histogram touch each other, they do not overlap. This is to ensure that each number only falls in one group. The...

...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...

Health Care Spending Demographics
U.S. households spent, on average, a total of $2,976 on health insurance, medical services, drugs, and medical supplies in 2008. Hispanic, Black or African American, and Asian households spent less—and White households spent somewhat more–than the average. These averages are calculated with data collected from...

Learning Statistics
Statistical data has become an item that we see all around us in our everyday lives, from television programs talking about selling products or politicians using data to show how they perform in their jobs, in hopes to be reelected. Throughout the course in Statistics for Managers, I have learned many things on how the use of statistical information can...

include decision analysis, project scheduling and network models.
Chapter 1 illustrates a number of ways to summarise the information in data sets, also known as
descriptive statistics. It includes graphical and tabular summaries, as well as summary measures
such as means, medians and standard deviations.
Uncertainty is a key aspect of most business problems. To deal with uncertainty, we need a basic...

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...
