statistics and its role in psychological research
... Suppose that a single value is to be used to describe a set of data. This is a request for its typical or representative value in lay terms, but a request for an index of central tendency in statistical parlance. There are three such indices: mode, median, and mean. The mode is the value, which occu ...

Chapter 4. SAMPLING DISTRIBUTIONS
... Although a formula is given in Chapter 3 to calculate probabilities for binomial events, if the number of trials (n) is large the calculations become tedious. Since many practical problems involve large samples of repeated trials, it is important to have a more rapid method of finding binomial proba ...

... such as the population mean, µ, using data in a sample, such as the sample mean, x̄. That is, we might use the sample mean, x̄, to estimate the population mean, µ. The accuracy of this estimation depends on the sample size, n, and the variability of the data. We can better understand the uncertainty ...
