In your reflection you must comment on the following points:
- Which topics do you feel most confident about?
- Are there areas for improvement?
- How would you evaluate your participation on the module?
a)Explain the difference between a bar chart and a histogram. Point at least two characteristics.
b)Create one real – life example that involves simple or compound interest. Support your example with appropriate calculations.
TYPE YOUR ANSWER TO TASK 2 HERE] A) A Bar chart is an illustrative picture of data that are used to compare various types of data. A characteristics of Bar chart includes discrete variables that presents categorical data. Bar charts do not touch each other and so has spaces between each bar. whereas the Histogram is the graphical representation that shows data in form of a bar to illustrate numerical data frequency and quantitative data. The characteristics of Histogram and are connected to each other, so has no space and the delivery of non-discrete variables, and histograms are grouped together in elements which are said to be ranges.
