Kasey MurphyParticipant
Yes, definitely helps! thank you!
Kasey MurphyParticipantThank 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.
Kasey MurphyParticipantThank 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
independent variable”Kasey MurphyParticipantThat 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!
Kasey MurphyParticipantThank 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
Kasey MurphyParticipantI 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/mm3Kasey MurphyParticipantCould 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!
Kasey MurphyParticipantThank 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.
Kasey MurphyParticipantSORRY — why evaluative tests are usually criterion referenced
Kasey MurphyParticipantAlso, can you explain criterion referenced & why discriminative tests are usually criterion referenced?
Kasey MurphyParticipantWhat 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
