Intelligence FRQ

Question 1

mean

Answer 1

average piece of data

Question 2

median

Answer 2

middle piece of data in a list of info in ascending or descending order

Question 3

mode

Answer 3

data that appears most frequently

Question 4

skewed distribution

Answer 4

frequency data is not spread evenly on a graph
ex. lots of data clustered at one end

Question 5

normal distribution (relate to mmm)

Answer 5

data spread evenly on the graph
-m,m,m would all be equal and placed in center

Question 6

positively skewed distribution (relate to mmm)

Answer 6

long tail of data that extends to the right
-mean greater than median and median greater than mode

Question 7

how are scores distributed on an intelligence test with a mean of 100 and standard deviation of 15?

Answer 7

the scores are distributed one standard deviation away from the mean, falling somewhere between 85 to 115, which is considered average for IQ testing.

Question 8

can an individual in group I have a higher score than the mean score for group II?

Answer 8

yes because 100 is the average of every group I member’s score, meaning there are scores both below and above 100. So, it is very possible that an individual in group I has a higher score than 115, group II’s mean.

Question 9

why are norms for standard intelligence tests periodically updated?

Answer 9

Standardized intelligence test scores may change over time, so norms make sure that scores are being standardized to the most recent groups.

Question 10

how to determine whether an intelligence test is biased

Answer 10

When comparing scores from two different groups, if a difference exists, the test is biased. If no difference exists, the test is not biased.
