Maths Coursework-relationship between heights and weights of 50 girls in year 11 HYPOTHESIS: I think that as the height of the girls increases the weight will as well, so I expect my graph to have a slight positive correlation. METHOD: From my data I selected the results for year 11 females. I then numbered each one from 1 - 86. I deleted the outliers and then randomly selected 50 results. I then plotted these results on a scatter graph. For my comparison, I did the same but with 50 year11 males. After plotting the graph I then added a trend line and found the square of the correlation coefficient and the equation of the trend line. From this I could then find out the correlation of my graph. RESULTS: Height (m) Weight (kgs) 1.67 52 1.72 51 1.69 51 1.65 42 1.68 47 1.62 51 1.63 52 1.68 50 1.55 60 1.59 42 1.73 48 1.65 54 1.52 44 1.52 48 1.67 48 1.55 39 1.73 50 1.72 51 1.61 54 1.75 60 1.37 40 1.55 50 1.60 48 1.56 45 1.70 60 1.68 47 1.55 50 1.59 45 1.70 54 1.62 56 1.73 64 1.62 54 1.61 54 1.63 45 1.65 54 1.80 42 1.69 54 1.63 48 1.62 38 1.72 51 1.54 65 1.69 42 1.60 55 1.83 60 1.63 44 1.56 50 1.65 54 1.70 50 1.68 48 GRAPH: COMPARISON: Height of year 11 girls (m) Weight of year 11 girls (kgs) Height of year 11 boys (m) Weight of year 11 boys (kgs) 1.67 52 1.62 52 1.72 51 1.55 36 1.69 51 1.6 48 1.65 42 1.49 37 1.68 47 1.64 55 1.62 51 1.6 41 1.63 52 1.63 52 1.68 50 1.57 38 1.55 60 1.35 51 1.59 42 1.63 47 1.73 48 1.59 48 1.65 54 1.6 46 1.52 44 1.6 51 1.52 48 1.55 66 1.67 48 1.57 62 1.55 39 1.58 55 1.73 50 1.68 36 1.72 51 1.71 54 1.61 54 1.55 52 1.75 60 1.49 52 1.37 40 1.62 54 1.55 50 1.7 47 1.60 48 1.54 54 1.56 45 1.55 40 1.70 60 1.75 65 1.68 47 1.6 46 1.55 50 1.64 40 1.59 45 1.57 48 1.70 54 1.62 54 1.62 56 1.62 58 1.73 64 1.68 57 1.62 54 1.6 46 1.61 54 1.51 48 1.63 45 1.53 40 1.65 54 1.62 41 1.80 42 1.61 38 1.69 54 1.69 48 1.63 48 1.51 65 1.62 38 1.5 54 1.72 51 1.52 41 1.54 65 1.7 52 1.69 42 1.70 49 1.60 55 1.59 46 1.83 60 1.53 48 1.63 44 1.62 54 1.56 50 1.67 51 1.65 54 1.55 36 1.70 50 1.65 49 1.68 48 1.65 54 CONCLUSION: From my results I...
