A graph is a really useful way to see how the data is distributed.

Draw a graph of Reaction time that is well-presented with the correct scale, axes and has a caption.

Upload the graph as an attachment (Accepted file types = .bmp .jpeg .jpg .png .pdf .docx or .doc).

Answers to FAQ for this question:

1. No other variables are required in this graph - only "Reaction time".
2. Part of the purpose of this question is for you to figure out what type of graph is appropriate & then graph it.

Indicate if this statement is True or False in regards to the graph and statistics obtained so far.

The graph shows a fairly normal distribution, and the values of the mean & median are fairly similar. Hence, the mean is an appropriate statistic to describe reaction time.

What is the median of the sample? (4 decimal places)

Time to identify the appropriate numerical summaries to describe the typical reaction time of individuals in Sunnyville.

What is the mean of the sample? (4 decimal places)

Let’s have a look at Gender as a variable with Reaction time: Slow and Quick.

After creating your graph, select the graph below which best represents your data.

The graphs in the previous question are a good way to look at the data but are not complete. How could you improve the graph in the question above? (Select all that apply)

Using your results so far, interpret your data from the Sunnyville sample of 100:

Before we start our analysis we need to understand our population and the sampling methods used.

The Sunnyville sample was obtained by stratified random sampling with the strata based proportionally on age groups. This type of sampling may be necessary for investigating the average reaction time.

Which of the statement(s) below is/are true regarding stratified random sampling for the research question?
