Terman
IQ= mental age/ chronological age x 100
1 of 11
More important than central tendency
Spread
2 of 11
Standard error
Standard deviation of multiple sample means - SD/ square root of n
3 of 11
Central limit theorem
large sample size- likely to be normal
4 of 11
Confidence intervals
estimate of standard error to create acceptable boundaries- work out mean of each sample and construct confidence intervals so that 95% of samples have means in the confidence intervals
5 of 11
Upper bound
Mean+ (1.96 x SE)
6 of 11
Lower bound
Mean- (1.96 x SE)
7 of 11
Further the boundaries are apart
lower the representativeness of the sample
8 of 11
higher the confidence interval
further from the mean but more samples should contain population mean between boundaries
9 of 11
Z- score
How many SDs you are from the mean
10 of 11
Can use to
Find probability of how many scores you might expect to find, use probability distribution and percentage of z-scores to identify statistical significance/ use standardised scores to compare to different data sets
