1
The Spread Of Disease Year 11 Survey

2
What we did… Hypothesis: To identify the spread of disease in a secondary school and to find whether transport, gender and sociability affect the rate at which disease spreads Prediction: Those who take the bus and come in contact with more people are more likely to spread disease. Males and females will have similar results Randomly chosen class (Year 11) Sample: 27 Students Mixture of genders Surveyed their movements and actions

3
The Participants Of the 27 surveyed the majority of the class were female The group sampled, as expected, were mostly 15 year olds since most of the academic year has not yet passed Age 15 – 6 Age 16 – 4 Age 15 – 9 Age 16 – 8 Male – 10 Female – 17

4
Distance Travelled It was unexpected that on average the participants travelled similar distances both on weekdays and weekends Weekday Weekend

5
Distance Travelled (continued) How far Year 11's travelled (Weekend) 0 5 10 15 20 25 30 051015202530 Distance (Miles) People Series1 The spread of the quartiles is very similar with the median almost exactly the same too

6
Transport Using the data from before we have understood that the students are more likely to contract diseases than average seeing as they use modes of transport that can carry multiple people therefore we can assume it is easier for the contingent to spread Car Bicycle Walking Taxi Bus

7
Contact From this data we have identified that males, considering the original proportion of males to females, come into contact with more people than females. We can therefore infer that males are more likely to contract various diseases Weekday Weekend

8
Vaccinations Males TreatmentNumberFemales TreatmentNumber Yes2 4 No8 13 Overall considering the distances travelled, the number of people they come into with and whether they have had a vaccination we conclude from the evidence we have collected that MALES are more likely at risk of catching a disease Yes No

9
Improvements & Constraints Improvements Survey a larger sample Compared results in more detail using advanced programs and methods Constraints Time limit The restrictions of the questionnaire

10
The follow up… Using the data we have gathered we hope to compare the results of a secondary school to those of a primary school After this we would like to publish a guide on how to minimize the risk of spreading disease whilst considering other factors such as practicality, economic issues and environmental issues
