There are Many Ways to Analyze Data

Some of the different types of graphs and charts used

 

 

DOT PLOT-A dot plot is a type of graphic display used to compare frequency counts within categories or groups. As you might guess, a dot plot is made up of dots plotted on a graph.

 

 

PICTOGRAPH- Visual presentation of data using icons, pictures, symbols, etc., in place of or in addition to common graph elements (bars, lines, points).

HISTOGRAM-A graphical display where the data is grouped into ranges (such as "40 to 49", "50 to 59", etc), and then plotted as bars.
Similar to a Bar Graph, but in a Histogram each bar is for a range of data and there are not spaces between the bars.

PIE CHART-a type of graph in which a circle is divided into sectors that each represent a proportion of the whole.

BAR GRAPH-  a diagram in which the numerical values of variables are represented by the height or length of lines or rectangles of equal width.

Data Analysis Definitions

Here are some of the most frequently used terms relating to data analysis:

MEAN
The mean is the numerical average of the data set. It is found by adding the numbers in the
data set together and dividing the sum by the number of data pieces in the set.

Ex. Lets say that I have 8 students.  The ages of my students are 5,7,8,12,15,11,9,13
First, I add all of the ages together.  The answer is 80.  Next, I divide 80 by the number of students, which is 8.  so 80/8 is 10.  My mean, or average, is 10.

MEDIAN
The median is the middle value of a data set in ranked order. If there is an odd number of
pieces of data, the median is the middle value in ranked order. If there is an even number of pieces of data, the median is the numerical average of the two middle values.  
Ex. Lets use the same numbers for the Age of my students, but remember to place them in least to least to greatest order.  5,7,8,9,11,12,13,15  If we have 8 students, then the number in the middle is actually two numbers 9 and 11.  What we would have to do is add the 9 and 11 for a total of 20 and divide the 20 by 2.  The median is 10.  If I had an odd number of ages, then the number in the middle would be the median.  5,7,8,9,     11,     12,13,15,16  the number 11 is directly in the middle with the same amount of numbers on each side.
 
MODE
The mode is the piece of data that occurs most frequently. If no value occurs more often than
any other, there is no mode. If there is more than one value that occurs most often, all these most-frequently-occurring values are modes. When there are exactly two modes, the data set is bimodal.

Ex. For 2, 3, 4, 5, 5, 6, 7, 8, 8, 8, 9, 11, the mode is 8.  For 2, 3, 4, 5, 5, 5, 7, 8, 8, 8, 9, 11, the modes are 5 and 8 (bimodal) which means that there are two modes this group of numbers. For 2, 3, 4, 5, 6, 7, 8, 9, 11, 13, 17, there is no mode.

What is Math?

To me, now that I appreciate math, it is like a game.  Figuring out different combinations to see why the answer is the answer is fun.

One of the most difficult areas in math, for me, was Data Analysis.  As a child, I confused median and mean, did not know how to determine percentages for a pie chart/graph, and really just did not want to give math a chance. 

As I have grown older, and had better teachers, all of the little things that I did not understand now make sense. 

Math, to me, is power.  Being able to double check a figure provided by a professional car salesman, or a billing cycle breakdown, or a forecast, etc.  Having an understanding of the relation of math to my daily life empowering.

Who am I?

My name is Launa Rose and I am an addict.  I have enjoyed math for 3 years.  I love being outside, learning new things, remembering the things I learned, and laughing.  I used to despise math, until I found out that I was actually good at it. I am married to a wonderful man and my first year anniversary is coming up in March 2015. 

I hope to teach children with special needs.  I believe that any child can succeed and should be encouraged to reach beyond what their expectations are, and discover what they are truly capable of.

I am an optimist, and I love to manipulate the possibilities of life.
