question 45

Multiple Choice

How accurately the standard normal curve model predicts the actual relative frequency of raw scores depends on three aspects of the data:

• B)50% of the raw scores are above and below the median;there is a large sample N;and the raw scores are measured on an ordinal,interval,or ratio scale.
• C)50% of the raw scores are above and below the median;there is a moderately large sample N;the raw scores are theoretically continuous scores measured on an interval or ratio scale.
• D)The raw scores form an approximately normal distribution;there is a moderately large sample N;and the raw scores are measured on an ordinal,interval,or ratio scale.
