QUESTION 1: variation The researcher wants to record the typical wingspan of the M. galathea in the UK, so that they can compare it to previously studied European populations. The table below represents measurements to he nearest mm, taken from 240 butterflies: Wingspan (mm) In the first two questions, an ecologist is studying the population of marbled white butterflies on the South Downs. Marbled white: Melanargia galathea 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 Number of butterflies 0 0 1 3 5 9 14 21 32 42 56 35 17 4 1 a) Based on the data, calculate the range (highest minus lowest), mean, median and mode. Ensure you show your workings or an explanation b) Based on your analysis, how would you describe the distribution of wingspan in Marbled White butterflies? Normal, bimodal or skewed? Explain your choice fully.
