BASIC DATA ANALYSIS INTRODUCTION Two types of analysis based on the data that is generated. Quantitative or Qualitative Basic descriptive statistics such as mean, median, and mode are in studying quantitative data. Standard deviation is also often used to show the variation Qualitative data is most often transcribed and studied for themes. REPORTING SCORES Don’t share data unless it is supporting a claim or idea. Reporting data without context or purpose is very confusing. Can give a visual breakdown of what was said and may be less confusing to those reading it. Keep in mind that you may want to arrange and show the results from your surveys. BASIC QUANTITATIVE DESCRIPTORS The mean (or average) is found by taking the sum of the numbers and then dividing by how many numbers you added together. The number that occurs most frequently is the mode. When the number are arranged in numerical order, the middle one in the median. TOPIC ONE The mean (or average) is found by adding all the numbers and then dividing by how many numbers you added together. Example: 3,4,5,6,7 3+4+5+6+7= 25 25 divided by 5 = 5 The mean is 5 TOPIC TWO The number that occurs most frequently is the mode. Example: 2,2,2,4,5,6,7,7,7,7,8 The number that occurs most frequently is 7 The mode is 7 TOPIC THREE When numbers are arranged in numerical order, the middle one is the median. Example: 3,6,2,5,7 Arrange in order 2,3,5,6,7 The number in the middle is 5 The median is 5 AVERAGING GRADES 5/24/2017 Lowest 55 60 75 80 80 80 83 83 93 93 93 93 93 Highest FIND THE MEAN OF THE FOLLOWING SET OF GRADES First add all the grades together. The total equals 1061 Now divide 1061 by 13 (total grades The answer is 81.61 The mean is 81.61 Lowest 55 60 75 80 80 80 83 83 93 93 93 93 93 Highest FIND THE MODE OF THE FOLLOWING GRADES The mode is the number which occurs most often. The number which occurs most often is 93 The mode is 93 Lowest 55 60 75 80 80 80 83 83 93 93 93 93 93 Highest FIND THE MEDIAN OF THE FOLLOWING NUMBERS The median is the number in the middle of numbers which are in order from least to greatest. If we count from both sides the number in the middle is 83. The median is 83 Lowest 55 60 75 80 80 80 83 83 93 93 93 93 93 Highest REAL LIFE If these were your math grades, what would you learn by analysising them? The mean was 81.61. In order to raise your grades, you would have to make higher than an 81.61 on the rest of your assignments. The mode was 93 which was your highest grade. You could look at these papers to see why you made this grade the most. The median is a 83. This means that most of your grades were higher than your average. Find your week area and try to improve. HOW DOES THE DATA HELP YOU Knowing the mean, median, and mode will help you better understand the scores on your survey. This in turn will allow you to report on significant findings or describe how your respondents feel about a specific aspect of the program being evaluated. 5/24/2017 ANALYSIS SOFTWARE Creating descriptive data can be done using a variety of programs. MS Excel is a simple program with many of the basic data analysis components built into it. SPSS is another software program that can do very simple as well as very complex statistical analysis. 5/24/2017 ANALYZING QUALITATIVE DATA Can be done using a saturation or thematic model. Transcripts are reviewed for common or recurring themes. These themes can then be grouped together and a more focused analysis of what is being said can occur. Selected quotes can be used to support themes. 5/24/2017
