THE t TEST

چکیده
The distribution of continuous data can often be closely approximated by the normal distribution (1). For example, the distribution of Cobb angles for scoliotic females may be represented by a normal distribution with a notional mean (μ) = 15 degrees and a notional standard deviation (σ) = 5 degrees, and is shown in figure 1. By assuming that these Cobb angles follow a normal distribution, we are able to answer questions such as ‘What is the probability that a randomly chosen scoliotic female has a Cobb angle less than 20°.
