size

Pg 1

Answer 1

• copybook = 3mm in height for mid zone letters
• small = less than 2.5 mm in height
• large = more than 4 mm in height

Question 2

To find the most frequent mid zone height

Pg 1

Answer 2

use:
mode
median
mean

Question 3

Mode

Pg 1-2

Answer 3

• one that occurs most frequently*
• to get:
  1. measure about 50 letters for the height of mid zone letters over various lines (does not have to be consecutive lines)
  2. tally up what size they are and find the most frequent one

Question 4

Bimodal distribution

Pg 2-3

Answer 4

-when distribution has two modes that are equal
-relatively rare
-usually occurs in highly functional people
Means:
-the writer behaves in accordance w/ the higher of the two modal scores generally, but goes to the other one at times as well (ie when stressed perhaps)

Question 5

Multimodal distributions

Pg 3

Answer 5

-if a distribution has more than two modes

Question 6

The median

Pg 3

Answer 6

• 50th percentile - the score in the middle*
• to determine average the middle scores or choose the middle score
• often used when distribution scores is pos or neg skewed

Question 7

The mean

Pg 3
