INC3701 Assignment 4 (COMPLETE ANSWERS) 2024 (867676) - DUE 24 July 2024 A study has been conducted to determine if there is a difference between biofilm scores of a sample group before and after using Mighty Mouthwash. The study will take place over an 8 week period. The group will be instructed to brush and floss, as normal, for four weeks without using the rinse and then to continue for four weeks using the rinse every morning. Three hygienists will collect daily biofilm scores and compare the scores of the group for the four weeks before the use of the rinse and four weeks after the use of the rinse. The dependent variable in the study is: a. Biofilm score b. Mighty Mouthwash c. Tooth brushing method d. Cannot be determined with the given information - ANSWER-a. Biofilm score A study has been conducted to determine if there is a difference between biofilm scores of a sample group before and after using Mighty Mouthwash. The study will take place over an 8 week period. The group will be instructed to brush and floss, as normal, for four weeks without using the rinse and then to continue for four weeks using the rinse every morning. Three hygienists will collect daily biofilm scores and compare the scores of the group for the four weeks before the use of the rinse and four weeks after the use of the rinse. The independent variable in the above study is the: a. Mighty Mouthwash b. Biofilm score c. Tooth brushing method d. Cannot be determined with the given information - ANSWER-a. Mighty Mouthwash A study has been conducted to determine if there is a difference between biofilm scores of a sample group before and after using Mighty Mouthwash. The study will take place over an 8 week period. The group will be instructed to brush and floss, as normal, for four weeks without using the rinse and then to continue for four weeks using the rinse every morning. Three hygienists will collect daily biofilm scores and compare the scores of the group for the four weeks before the use of the rinse and four weeks after the use of the rinse. The three hygienists reviewed the criteria for utilizing the index, they were able to record the same conditions the same way. This is an example of: a. Interexaminer reliability b. Intraexaminer reliability c. Internal validity d. External validity - ANSWER-a. Interexaminer reliability A study has been conducted to determine if there is a difference between biofilm scores of a sample group before and after using Mighty Mouthwash. The study will take place over an 8 week period. The group will be instructed to brush and floss, as normal, for four weeks without using the rinse and then to continue for four weeks using the rinse every morning. Three hygienists will collect daily biofilm scores and compare the scores of the group for the four weeks before the use of the rinse and four weeks after the use of the rinse. What can be done to BEST increase interexaminer reliability between the three hygienist? a. Calibrate the examiners b. Use the same measurement tool c. Monitor the same independent variable d. Retain the same test subject - ANSWER-a. Calibrate the examiners A study was conducted to determine which mouthwash killed the most bacteria in the mouth. In this study, the mouthwash is considered to be which kind of variable? a. Independent b. Dependent c. Experimental d. Estraneous - ANSWER-a.
