Question

In this exercise, you will practise organising data in the best way. You will also think about the meaning of the word 'correlation', and practise using data to support an argument. The gestation period of a mammal is the time between fertilisation and the birth of a baby animal. It is the time during which the young animal develops inside the mother's uterus. The table shows the mean mass of an adult female of eight different species of mammal, and the mean gestation period for that species. Species moose (elk) llama goat wolf lion rabbit elephant chimpanzee Mean mass of a female / kg 550 113 15 40 150 1 5000 40 Mean gestation period/days 245 330 150 64 108 33 640 227 In the table below, rearrange the data so that it is easier to see if there is a relationship between the mean mass of a female and the mean gestation time.​

Answer 1

The data can be arranged in a scatter plot or a table.

Data arrangement

To better analyze the relationship between the mean mass of a female mammal and the mean gestation period, the data can be rearranged into a scatter plot or a table where the two variables are clearly presented. A table that organizes the data can be found attached.

This table makes it easier to observe and compare the mean mass of a female mammal with its corresponding gestation period. It provides a clearer overview of the data for further analysis and identification of any potential relationships.
