... Remember that we use statistics (information about a sample) to estimate parameters (information about a population. There are 2 types of estimates: o point estimate – the statistic itself parameter is almost never exactly equal to point estimate o interval estimate – a range of scores given ...

Lecture 33-Statistical significance using Confidence Intervals
... -- Can we make any statements about the population mean ? -- We cannot say that population mean is 175 cm because we are uncertain as to how much sampling fluctuation has occurred. -- What we do instead is to determine a range of possible values for the population mean, with 95% degree of confidence ...

The typical comparison of two distributions is the comparison of means. If we can safely make the assumption of the data in each gr ...
