Abstract
This chapter gives the methods and tools for the estimation of parameters, which includes the
point estimation and interval estimation. The confidence interval includes the construction of 100(1−α)%
interval limits for, single population(one sample) mean µ, the difference between two population means
(independent sample) µ1 − µ2 for equal and unequal variances, the confidence interval for paired samples(related samples). The procedures to perform these methods on SPSS are given.
Keywords: Point estimation, Interval estimation, One sample t-test, Independent sample t-test, Paired sample t-test.
