idea of how large his sample size needs to be to ensure a reasonable accuracy of results. * When to Use Slovin’s Formula * If a sample is taken from a population‚ a formula must be used to take into account confidence levels and margins of error. When taking statistical samples‚ sometimes a lot is known about a population‚ sometimes a little and sometimes nothing at all. For example‚ we may know that a population is normally distributed (e.g.‚ for heights‚ weights or IQs)‚ we may know that

Hypothesis The greater the percentage of acetylsalicylic acid (ASA) in the tablet‚ more powerful and efficient the aspirin would be due to the way aspirin works in human’s body. Aspirin is often used to alleviate the pain‚ and the sensation of pain is mainly attributed to a chemical substance called prostaglandins‚ which is responsible to send a strong signal

SAMPLING TECHINIQUE PROBABILITY SAMPLING Having chosen a suitable sampling frame and established the actual sample size required‚ you need to select the most appropriate sampling technique to obtain a representative sample. The basic principle of probability sampling is that elements are randomly selected in a population. This ensures that bias is avoided in the identification of the elements. It is an efficient method of selecting elements which may have varied characteristics‚ as the process

demand in the future and containing the resources available on hand to do this. The challenge is not only to come up with the future demand and the efficient manufacturing design but also to beat the lead times in between the chains in the systems. The errors can be costly in this process. Overshooting in the forecasts will result in inventory costs in the factory‚ where underestimating will cause late orders‚ extra labor costs‚ missed sales opportunities‚ stockout costs‚ and even production close downs
