Yes, definitely helps! thank you!
Thank you, I will get my old Campbell text from school out and glance over that chapter quickly before test day. I have been using the newest edition.
Thank you! I found your explanation to be quite helpful.
Could you also explain or give an example of:
“R squared (or Coefficient of Determination): Measures the percentage of variation in the
values of the dependent variable that can be explained by the variation in the
That does help! i also had a lengthy discussion with my co-workers on the topic, which also helped. Thank you for the time you spend in helping understand this… less than 3 weeks to test day!
Thank you.. I have to read over it multiple times, I don’t know why these terms always seem to confuse me.
When you give the example of the TIMP – Specificity is higher –Likelihood that someone who does not have the condition will be negative on the diagnostic test; refers to the percentage of children without problems who are correctly identified as such; — so with the TIMP, when looking at Specificity, we are looking at the percentage of children without the the condition who are correctly negative on the test, and ruling out a condition — so we are ruling out GM delay with the TIMP Score —
But I am still confused by the explanation of TIMP: “indicating that it is a good measure for detecting large numbers of high risk infants who are not developing typically” — this seems like sensitivity – we are are identifying infants not developing typically (those who have GM Delay)?
Sorry, this topic as had me since PT school
I have this table from Cambell’s if similar?
TABLE16.4 Normal Ranges for Key Blood Parameters
From Garritan S, Jones P, Kornberg T, et al: Laboratory values in the intensive care unit, Acute Care Perspect 3:7-11, 1995.
Types of Cells Purpose Symptoms Normal Ranges
White blood cells (leukocytes) Fight infection Leukopenia infections 4–11 k/ul
Neutrophil (absolute neutrophil count [ANC]) Fight infection Leukopenia infections 1500–8000 cells/ml
Red blood cells (erythrocytes) 3.8–6 million cells/ul
Hemoglobin 150,000–400,000 cells/mm3
Could you post these in a table? I have found the other study guides quite helpful. I actually do not have the Effgen text (have been using the other recommended texts). I cannot access the second reference.
Thank you! that explanation was incredibly helpful .I also got out our Peabody Manual — have never realized that standard score for Peabody are also based on 10 being at the 50th percentile of a bell curve.
SORRY — why evaluative tests are usually criterion referenced
Also, can you explain criterion referenced & why discriminative tests are usually criterion referenced?
What are the normative values for Bayley? Especially in reference to a practice test question where a 40 month old child scored scale score of 9
