Half of the hotel may render breakfast service for the customers hence let us take P as 0.5. We need to find how many hotels provide breakfast in X. Recently, Kothari (2001) reviews event studies in the accounting literature.Determining Sample Size for Probability Samples Financial, Statistical, and Managerial Issues -As a general rule: -The larger the sample, the smaller the Budget.Assume a hill station X has a total number of 52 hotels. Jensen and Ruback (1983), Jensen and Warner (1988), and Jarrell, Brickley and Netter (1988) survey corporate control events. Smith (1986) presents reviews of event studies of financing decisions. Summaries of long-horizon tests in Kothari and Warner (1997) and Fama (1998).For 95 % of the confidence value, the Z value will be 1.96 per the normal table. The sample size was determined depending on a standard formula used to determine samples size (formula 1) ( Kar and Ramalingam, 2013 ).Assuming this is the normal distribution, let us find the Z value from the Z table. Calculate Sample Size using the information:This sampling technique gives an equal opportunity to each of the potential participants, which help to get higher sample representativeness and more confident results (Kothari, 2004, Robson, 2011).
Z value can be called a Z score or Standard Score value. Sample Size = 1.33 / (1 + ((1.33 – 1) / 52))For this data set, the appropriate Sample size is 1.32 ExplanationStep 1: Note down value. Sample Size =(1.96 2 * 0.5 * 0.5) / (85%) 2 According to Kothari 2004 descriptive research studies are.Sample Size is calculated using the formula given below 8 7 Estimation and Sample Size. Wwe 2k 17 download freeThe Z score has some basic formula too.Here, X is the total number of population and M is the mean of the population, and σ is the standard deviation. Generally, you can note this value from the Z table. So Z score is the total number of standard deviations it has before and after that mean data point. That is, say you have a particular population size, and it has some mean which is a data point. ![]() ![]() Sample Size Formula CalculatorYou can use the following Sample Size CalculatorSample Size Formula in Excel (With Excel Template)Here we will do the example of the Sample Size Formula. It is very easy and simple.Below are the two different sets of data. This part of the population will be taken as a random sample. Hence for a chosen percentage amount of the whole population, the survey will be carried out. Taking 1 out of millions will not yield you correct result, too hence leading to negative results, which is a Type II error. ![]() We also provide a Sample Size calculator with a downloadable excel template.
