Q

Outline one strength of using the standard deviation rather than the variance as the measure
of dispersion for the data collected in this study

A

The standard deviation is the square root of the variance. The advantage of this is that the answer is a figure that is much more typical of the actual difference (actual data collected) in the amount of snacking taking place with or without eyes on the fridge. The variance is a much bigger (untypical) figure as it is the sum of the differences in each individual’s snacking compared to the mean which is then squared (squaring makes
the answer a much bigger figure).

Q

Explain what ranking data means.

A

assigning numbers to a denote position in an ordered sequence, lowest to highest (vice versa). E.g. rank 1 would be for the smallest number in data whilst rank 20 for the highest.

17
Q

Why is it better to use median than mean occasionally?

A

data contains outliers. The median is the less sensitive measure of central tendency when there are outliers.

18
Q

Which inferential stats test can the sample be different in each condition?

A

Mann Whitney U

19
Q

Identify 2 criteria for using a parametric test to analyse data.

A

-no extreme scores
-level of data must be at least interval
