Sample size The process of determining the proper sample size was established through a series of calculations and after obtaining all the possible sample sizes‚ the largest one was taken into consideration to collect the closest number to a representative sample of the population. The following two equations where used: Equation 1: N=z2 *(p.q) E2 N= sample size Z=level of confidence interval at 95% so z=1.96 P=estimated percent of population E=acceptable sample error expressed

statistics‚ a sample is a subset of a population. Typically‚ the population is very large‚ making a census or a complete enumeration of all the values in the population impractical or impossible. The sample represents a subset of manageable size. Samples are collected and statistics are calculated from the samples so that one can make inferences or extrapolations from the sample to the population. This process of collecting information from a sample is referred to as sampling. A complete sample is a set

Calculating Sample Size Types of Samples Subjective or Convenience Sample - Has some possibility of bias - Cannot usually say it is representative - Selection made by ease of collection Simple Random Sample - No subjective bias - Equal chance of selection; e.g.‚ select the fifth chart seen on every third day - Can usually be backed to say it is representative Systematic Sample - Is a random sample - Equal chance of selection due to methodology; e.g.‚ computer-generated list of

Determining Sample Size In the business world‚ sample sizes are determined prior to data collection to ensure that the confidence interval is narrow enough to be useful in making decisions. Determining the proper sample size is a complicated procedure‚ subject to the constraints of budget‚ time‚ and the amount of acceptable sampling error. If you want to estimate the mean dollar amount of the sales invoices‚ you must determine in advance how large a sampling error to allow in estimating the population

RELIABILITY‚ VALIDITY AND REPRESENTATIVE SAMPLE IN RESEARCH John and Webb (2002‚ p.148) distinguishes between validity and reliability‚ arguing that the first one is the extent to which a research is capable of measuring what it is supposed to be measuring and the second one is the extent to which a research delivers consistent results. Validity and reliability measurement instruments are free of bias and random error. Haynes and Heiby (2004‚ p.47) propose some questions addressing sampling adequacy
