Exploratory research helps determine the best research design‚ data collection method and selection of subjects. It should draw definitive conclusions only with extreme caution. Given its fundamental nature‚ exploratory research often concludes that a perceived problem does not actually exist. Exploratory research often relies on secondary research such as reviewing available literature and/or data

The first step for this is to calculate the standard error (see slide 7-6); provide the value below. 272.84 / SQRT(31‚634) = $1.53 d. The second step in calculating the margin or error (often simply called error) is to multiply the standard error by 1.96; provide the value below. 1.96*$1.53=$3.

determine their actual demand based on historical forecast errors. The historical forecast errors were computed for each item in the previous year and the frequency of these errors. The frequency of past forecast errors was used as a probability distribution for the future errors. For example‚ in the past year‚ if there were 50% of the forecast errors for “new” items were between 0.7 and 1.6. Then the company can assumed that the forecast errors for “new” item in the current year also would be between

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

study focuses on the way in which error correction is done and the significance of errors in the Romanian context. In designing it‚ I did not use my knowledge on causes of errors as I was not interested to find out whether it can be established a correlation between students’ mother tongue‚ the target language and the production of errors. I oriented this study towards a narrower issue: the attitudes of teachers‚ students and native speakers of Romanian towards error correction. In order to do this
