Document Summary
Measures the average of scores(deviation) from the mean. It takes into account all scores in the distribution and not just the highest and lowest ones. The greater the variability or spread of scores, the higher the standard deviation. It provides a precise way of determining how people compare to one another on a given test new score standard scores percentage scores. Percentile scores: indicate the percentage of people who score of an below the score you obtained. Its a score that is compared relatively to rest of the people. Inferential stats: inferential stats provides us with a way of determining how much confidence we can have in results obtained from samples by telling us how likely it is that results are due to chance alone. Real: true of population=statistically significant probability level is what we look at if the results are statistically significant or not. Statistical cut off: if the results are lower than 0. 05 then the results are real-significant.
