observed frequencies and the frequencies we would expect‚ based on some theory? • Is there a difference between observed and expected proportions? • Is it reasonable to conclude that sample is drawn from a population with some specified distribution (normal‚ etc.). • Is there significant difference between some measures of central tendency (X bar) and its population parameter (μ). A number of tests may be appropriate in this situation‚ i.e. Parametric test and Non-parametric test. Parametric

Normal Distribution with Excel - Applications & Examples In my last post I discussed how to use the normal distribution function already added in MS Excel. In this post I will continue with the examples and we will how we use them. In this post i will not discuss the manual solution of the problem but only the Excel Based solution. The following problems are taken from Introduction to Statistics By Walpole‚ 13th Edition Chapter 07‚ Page 197-200. I wil elaborate how you can use excel formula

specifies if the scores are grouped closely around the mean or are widely scattered (Gravetter & Wallnau‚ 2013). The standard deviation provides researchers with information on the score standardization about the mean. This is important because‚ in a normal distribution‚ scores are symmetrically distributed with the highest frequency at the midpoint‚ and lower occurrences spread
