(average)

Median: The middle score across a range of scores

Mode: the most frequently occurring score/s

# data[].attributes.body
Median= middle score
Mode = most frequent score

# data[].attributes.body
Median = the middle score
Mode = the most frequent score
S.D = square root of the variance - allows you to compare distributions with different locations and spreads

# data[].attributes.body
Mode: The most recurring score

Median: the middle number in a set of scores when all put in order

# data[].attributes.body
Average, middle value, value with the highest occurance, how spread out the values are, Root(Sigma(X-Xbar)/N)

# data[].attributes.body
Mean= average of scores
Median= middle score
Mode= most occurring score
SD= how much variation there is in a set of scores
Calculate standard deviation= square root of the variance

The stats book (page 72) referred to a way to determining the median when there are duplication of the middle scores. Should we ignore this formula?
