behavior known as?
Assessment
Tests and inventories, rating scales, observations and interview data are tools for this process or procedure.
Assessment
Going beyond measurement to making judgments about human
attributes and behaviors
Appraisal or Evaluation
Making a statement about the meaning or usefulness of measurement
data according to the professional counselor’s knowledge and judgment
Interpretation
Any form of mental testing
Psychometric
Measures various factors in same test (ie: math, science)
Horizontal test
The arithmetic average
Mean
The middle score in a distribution of scores
Median
The most frequent score in a distribution of scores
Mode
All three of these fall in the same place when the distribution is normally
distributed
Mean, Median and Mode
What are the measures of central tendency?
Mean, Median and Mode
The degree to which a distribution of scores is not normally distributed
Skew
The right tail is longer; the mass of the distribution is concentrated on the left of the figure
Positive Skew
The left tail is longer; the mass of the distribution is concentrated on the right of the figure
Negative Skew
The highest score minus the lowest score
Range
The highest score minus the lowest score plus one
Inclusive range
The variability within a distribution of scores
Standard deviation
The mean of all the deviations from the mean
Standard deviation
Square of the standard deviation
Variance
Distributes the scores into six equal parts - 3 above the mean, 3 below the
mean
Normal Curve
68% - 34% above the mean, 34% below the mean
One standard deviation
95% - 13.5% above the mean, 13.5% below the mean
Two standard deviations
99% - 2% above the mean, 2% below the mean
Three standard deviations
Converts a distribution of scores into nine parts, with 5 in the middle and a standard deviation of about 2
Stanine
Uses to compare several different test scores for the same individual
Standardized score scale
These derived scores provide for constant normative or relative meaning,
allowing for comparisons between individuals
Standardized Scores
Express the person’s distance from the mean in terms of standard deviation of that standard score distribution
Standardized test scores
Standardized score where the mean in 0, SD is 1
Z score
Standardized score where the mean is 50, SD is 10
T score
Indicates % of people who answered an item correctly
Difficulty Index/Value
Higher the number, the easier the item
Difficulty Index/Value
What is the difficulty index/value if 25% answered correctly?
.25
A statistical index which shows a relationship between two sets of numbers
Correlation Coefficient
Represented by “r” and ranges from -1 to +1
Correlation Coefficient
A correlation between 2 variables
Bivariate
