If you see a line graph, the X variable should be

a. Continuous

b. Discrete (nominal)

c. Ordinal

18.Which of these can error bars be used to depict

a.Max/min,

b.Standard Deviation,

c.Standard Error,

d.95% CI (Confidence Interval)

e.All of the above

19.You have a graph in which the means and SD bars are depicted.In this graph the error bars for sample A do not overlap those for sample B.

a.You can conclude that there IS a difference between sample A and Sample B

b.You can conclude that there ISNOT a difference between sample A and Sample B

c.You can't conclude anything about the differences between means by looking at error bars that represent the SD of that data set

d.You can conclude something using SD error bars but it would need for the error bars to overlap for you to be able to draw that conclusion.

20.You have a graph in which the means and SE bars are depicted.In this graph the error bars for sample A do not overlap those for sample B.

a.You can conclude that there IS a difference between sample A and Sample B

b.You can conclude that there ISNOT a difference between sample A and Sample B

c.You can't conclude anything about the differences between means by looking at error bars that represent the SE of that data set

d.You can conclude something using SE error bars but it would need for the error bars to overlap for you to be able to draw that conclusion.

21.You have a graph in which the means and error bars representing a 95% confidence interval (CI) are depicted.In this graph the error bars for sample A do not overlap those for sample B.

a.You can conclude that there IS a difference between sample A and Sample B

b.You can conclude that there ISNOT a difference between sample A and Sample B

c.You can't conclude anything about the differences between means by looking at error bars that represent the 95% CI of that data set

d.You can conclude something using 95% CI error bars but it would need for the error bars to overlap for you to be able to draw that conclusion.

22.What effect does number of replicates have on error bar size?

a.More replicates means bigger error bars

b.More replicates meas smaller error bars

c.Replicate number has no effect on error bar size

23.On a graph when bars have lots of asterixes over them then you can conclude that they are highly similar to the control or comparison group.

True OR false
