B. Arrange your data in numerical order.
C. Calculate the five number summaries and summarise this information in a table.
D. ANALYSING …show more content…
This causes the shape of the box plot to be quite spread out with the median and quartiles close together. The female writing hand box plot is also the same length as the writing hand box plot; this is because the minimum and maximum data from the writing hand came from females. When putting the male and female writing hand box plots in comparison to each other, you can see that females have a much larger range than the males as discussed before. This causes the female box plot to have a lower, lower quartile and median and a higher upper quartile. The median for males is only slightly higher than the median for females, keeping in mind that males had data from an eleven (11) year old and females had data from a forty two (42) year old. This can cause the data to be slightly swayed as there were not equal age groups for both box …show more content…
Draw three different scatter plots.
B. Fit a line of good fit to the points
C. Determine a rule. Write rule clearly on your scatterplot
Head circumference was chosen as the predictor as it has the lowest deviation out of the three.
Rule: y = 3.5154x - 33.215
D. Analysing the data.
Overall a majority of the points are either on or close to the line, with only a couple ranging out slightly further away from the line. The graph comparing height and head circumference has more points that are 'close' to the line compared to the other two graphs. The reasoning to this is that there were fewer variations in the data from individuals. Seven points are below the trend line, five are above and three are sitting exactly on the trend line. The spread is overall fairly even on each side of the trend line, though below the trend line the points are slightly more spaced out than the points above the trend line.
