1 Making sense of data We got to deal with some Math here folks

2 Measures of Central Tendency

3 Measures of dispersion 3 types: Range, Interquartile Range & Standard Deviation

4 Interquartile Range Shows the middle 50% of a set of scores

5 Standard Deviation

6 Put your data into graphs Bar Graphs

7 Put your data into graphs Histograms are different from bar graphs because they are used for continuous data (test scores)

8 Put your data into graphs Frequency polygons is similar to a histogram as it shows continuous data but its advantage is that it can graph 2+ frequency distributions

9 Statistical Significance Probability (p) concerns the degree of certainty that an observed difference or relationship between 2 sets of data is a real difference rather than having occurred by chance. eg. If I flip a coin 100 times and it lands on heads 60 times A result is considered to be significant if it occurs 95% of the time, p 0.05 The lower the probability that it occurred by change the greater the significance
