A proposed option system involves usage of computer-assisted direction. In this method, all pupils view the same videotaped talk and so each is assigned to a computing machine terminus for farther direction. The computing machine guides the pupil, working independently, through the self-training part of the class. To compare the proposed and current methods of direction, an come ining category of 122 pupils was assigned indiscriminately to one of the two methods. One group of 61 pupils used the current programmed-text method and the other group of 61 pupils used the proposed computer-assisted method. The clip in hours was recorded for each pupil in the survey.
1. Use appropriate descriptive statistics to sum up the preparation clip informations for each method. What similarities or differences do you detect from the sample informations? 2. Use the methods of Chapter 10 to notice on any difference between the population means for the two methods. Discourse your findings. 3. Calculate the standard divergence and discrepancy for each preparation method. Conduct a hypothesis trial about the equality of population discrepancies for the two preparation methods. Discourse your findings 4. What decision can you make about any differences between the two methods? What is your recommendation? Explain 5. Can you propose other informations or proving that might be desirable before doing a concluding determination on the preparation plan to be used in the hereafter?
