  1. Answer:

    Step-by-step explanation:

    a)A bar chart is used when you want to show a distribution of data points or perform a comparison of metric values across different subgroups of your data. From a bar chart, we can see which groups are highest or most common, and how other groups compare against the others. A pie chart is best used when trying to work out the composition of something. If you have categorical data then using a pie chart would work really well as each slice can represent a different category.

    b)The Independent Samples t Test is commonly used to test the following: Statistical differences between the means of two groups. Statistical differences between the means of two interventions. Statistical differences between the means of two change scores.
