# concepts and basic data analysis 1

- Line graph
- Bar graph (horizontal or vertical bars are acceptable)
- Pie graph

**Suppose** you were presenting these graphs to a group of people (clients, co-workers, friends, etc.) who are not mathematically savvy.

**Create** a 7- to 10-slide presentation with speaker notes that provides a non-technical explanation of each graph. Remember, you are addressing people who probably do not like or understand mathematical terms.

For each graph, **include** the following:

- Screenshot of your graph.
- For the line graph, what are the labels on the horizontal and vertical axes?
- For the bar graph, what labels are on the bars? What is being measured in this graph? (Hint: look at the axis label.)
- For the pie graph, what is the title, in other words, what is it measuring?
- How would you improve each graph if at all? Is anything missing, misleading, or perhaps just wrong with this graph?
- What would be the appropriate measure(s) for central tendency (mean, median, mode) to display with each graph?
- What measure of dispersion (range, standard deviation) would be best?
- Provide a reference citation for the source of your graph so your facilitator can find the graph online.
*Note*: sometimes information changes from day to day on websites, hence the reason for the required screenshot in first bullet point above.
