- Values of IQ score are distrubted approximately according to a normal distribution with mean 100 and standard deviation 15. What proportion of the population has a value above 130? Below 85? Above 85?The heritability of intelligence as measured by IQ tests changes with socioeconomic status (SES). When participants are of high SES, heritability is high; when participants are of low SES, heritability is near zero. Which statement best explains this observation? monozygotic (MZ) twins occur less frequently amongst parents of high SES monozygotic (MZ) twins occur less frequently amongst parents of low SES there is greater variation in IQ scores amongst participants of high SES there is greater variation in IQ scores amongst participants of low SES heritability only applies to the specific population and specific environment in which it is measuredAre traditional IQ testing scales relevant today?
- An average IQ is between ______ - ______ , which is within 1 standard deviation of the mean. 100-150 90-110 75-125 85-115. IQ scores predict school performance. T or F?Give only typing answer with explanation and conclusion Which statistical test would you choose for the following hypothesis? "There will be a difference in scores on a measure of depression before and after taking part in a statistics lecture".
- How does IQ testing relate to the diagnosis of intellectual disability? below average IQ is necessary and sufficient for a diagnosis below average IQ is necessary but not sufficient for a diagnosis below average IQ is sufficient but not necessary for a diagnosis it does not relate to the diagnosisIdentify which one of the four types of validity: measurement validity, statistical conclusion validity, internal validity, or external validity-is it violated in each of the following scenarios? Explain your decision. After a successful Phase 3 clinical trial in which their new drug improved symptoms in children with asthma, the pharmaceutical company announced in a press release that it had developed an asthma drug that the whole family can use. As a test of intelligence, researchers administered a 40-question American history test to the study participants. The average Score was 15 correct out of 40, thus researchers concluded that study participants are not very intelligent.What type of variable would age be considered? Sex? Height? Income status? Options:Discrete, Nominal,Continous, Ordinal
- Select the type(s) of experiment (all that are correct): You are studying in detail a person with a large lesion in the temporofrontal lobe observational within-subjects correlational cross-sectional study quasi experiment factorial case study independent-samples (between-subjects)How might crystallized and fluid intelligence work together to help middle-aged people deal with new situations and problems? How do the apparent discrepancy between declining IQ scores and continuing competence would affect the learning ability of middle-aged adults who return to school?Hello, can Measure of infant intelligence will be of predictive of intellectual performance later.
