The autonomous factors of this venture were the various areas in school that microbes were being gathered from. The areas were the door handle at the flight of stairs, the door handle in the science room, the washroom sink, the restroom latrine, the cafeteria table, the cafeteria railing, the drinking fountain, the storage mix, the floor of the science room, and the corridor floor. The reliant variable was the quantity of states that developed from the microscopic organisms. The benchmark group is was the cafeteria table since it was continually cleaned. Quantitative information was utilized in this trial and the degree of information was ordinal. The ANOVA test was utilized to do the factual investigation of the information. The methods for the microscopic organisms states of every area were individually as follows: 32.6 for the flight of st airs door handle, 32.2 for the science room door handle, 44.2 for the washroom sink, 32.2 for the restroom latrine, 28 for the cafeteria table, 15 for the railing in the cafeteria, 30.6 for the drinking fountain, 21.8 for the storage mix, 24 for the science room floor, 15.8 for the corridor floor. The invalid speculation was if the various areas in school have no impact on the settlement checks of the microorganisms, at that point the midpoints of provinces will be somewhat the equivalent. The p-estimation of this analysis was 0.05, around 0.033. Because of the p-esteem the invalid theory was dismissed. The elective speculation was on the off chance that microscopic organisms are gathered from various areas in school, at that point the state checks of microorganisms will be the equivalent. The consequences of this analysis didn't bolster the elective speculation. As appeared underneath in Table 1: The Counts Of Colony Depend On The Locations In School, the standard varieties were th e accompanying: 7.89 for the flight of stairs door handle, 11.5 for the science room door handle, 26.8 for the restroom sink, 10.0 for the cafeteria table, 12.2 for the washroom latrine, 8.63 for the cafeteria railing, 13.9 for the drinking fountain, 8.41 for the storage mix, 14.0 for the science room floor, and 9.68 for the corridor floor. As appeared in Graph 1: The Average Counts of Colony, the normal tallies of settlement were appeared as following: 32.6 for flight of stairs door handle, 32.2 for science room door handle, 44.2 for washroom sink, 28 for cafeteria table, 32.2 restroom latrine, 15 for cafeteria railing, 30.6 for drinking fountain, 20.8 for storage blend, 24 for science room floor, 15.8 for corridor floor.

The elective speculation that the settlement tallies of the microorganisms would be somewhat the equivalent despite the fact that they were gathered from various areas was dismissed. The motivation behind why the outcomes didn't bolster the elective speculation was on the grounds that the state forgets about of the microscopic organisms went to be totally different. The most noteworthy number of settlement found in one petri dish was 84 and the least was 6. Just 3 out of 10 gathering normal were in the scope of 30 to 35 and just one gathering normal was higher than 40. These outcomes above were insufficient to help the elective speculation. To help the elective speculation 7 out of 10 gatherings needed to have the normal in a similar range. The free factor (the various areas that microscopic organisms were gathered from) had this impact on the n eedy variable (states) was on the grounds that it relied upon how grimy the areas were. On the off chance that one area was amazingly filthy like the washroom sink or latrine, the more microbes will be gathered and the more states will develop. As indicated by the writing survey, microorganisms would require in any event 24 hours to be noticeable. The microscopic organisms were guaranteed to be obvious and create the same number of provinces by leaving
