Words Per Minute vs Number of Errors By: Lexus Lander & Brad Anderson

Introduction Comparison between how many words someone can type in a short time period and how accurate they are. Does the speed of typing depend on the accuracy of what you are typing? We believe that the faster a student types, the more errors they will make. We will give twenty five students a minute to type as many words as possible. NO BACKSPACING!!!

Data Population- DuBois Area High School student body. Sample- 25 Students. Individuals- Students in our second period English class. Variables- Amount of words students can type per minute and how many errors they make. NO BACKSPACING!!!

Data Table

Graph

Analysis r= -.719 r^2= 0.517 Relation to equation- Shows the correlation and accuracy of the project. Correlation of graph- Represented by r, and is strong and negative. Accuracy- Represented by r^2, explained variation of the errors. Variation- 51.7%

Prediction Equation- y= -0.123x + 9.957 Average words typed per minute- 42 (based on our sample) We predict that if a student would type the average 42 words per minute, the number of errors made by them would be 5 (based on our sample). We also predict that the faster a person types, the less errors will be made with a 51.7% explained variation (accuracy).

Conclusion Hypothesis was incorrect. We believed that typing speed and amount of errors would have a strong, positive correlation. Our results ended up only being about 50% accurate. Correlation was -.719. Strong and negative. Possibly negative due to no backspacing. If backspacing, less errors and a positive correlation might have occured.
