Maths Mice Coursework
Mice Coursework Introduction In this coursework I am going to compare two sets of data about the weight of male and female mice. I am then going to make a hypothesis about the weights of these mice and then find out whether or not I am correct. Hypothesis My hypothesis is that male mice will be heavier than the female mice. I think this because usually males need to eat more and tend to be bigger. Grouping the Mice. In this coursework I will also have quite a few graphs. By making these graphs I can compare the data and then see if the results support my hypothesis or not. I will start of by put the mice into groups. By doing this it will save me a lot of time and make my data my easier to compare. Also grouping the data enables me to draw the graphs which help me to compare the data. After I group the data I will also find the mean average for both sets of mice. Female Groups Frequency (f) Midpoint (X) f x X 0 ? w < 5 5 ? w < 10 0 ? w < 15 5 ? w < 20 20 ? w < 25 25 ? w < 30 0 9 29 7 25 27 2.5 7.5 2.5 7.5 22.5 27.5 0 42.5 362.5 22.5 562.5 742.5 Total: 107 Total: 1932.5 So the mean average of female mice is 1932.5÷107= 18.10 (2 d.p. places) Male Groups Frequency (f) Midpoint (X)
To test my hypothesis, I will use primary data. I will collect information from same houses in Mepton Bridge. I will compare Mepton Bridge to the whole country using secondary data.
Handling Data Cycle Introduction: This project is about the sizes of families in the area where I live. I am going to investigate how my town, Mepton Bridge, compares with the whole country. People who do town planning need to know about the type of households in an area and use tis kind of information. For example when planning new schools, parks and play areas. Hypothesis 'The average number of children living in each house in Mepton Bridge, is higher than the country average' I think this because Mepton Bridge is a growing town with a lot of new houses and young families. Plan of Action To test my hypothesis, I will use primary data. I will collect information from same houses in Mepton Bridge. I will compare Mepton Bridge to the whole country using secondary data. I will count people who are less than seventeen years old as children. Because the town is too big to fid out the number of children in every house, I have decided to choose five streets at random from the 876 streets on the list on the A-Z map of Mapton Bridge. This might not work very well because the street may not have any Houses. For example one street might be in an industrial estate. I need to have streets in different parts of the town to covert he difference across the town. If I do not get enough houses, or all the streets are in part of Mepton Bridge, I might need to extend my sample by
