“The class width should be an odd number. This will guarantee that the class midpoints are integers instead of decimals”~ James Jones, Professor of mathematics, Richland Community College [2]. References Section 2.1, Frequency Distributions and Their Graphs Statistics: Grouped Frequency ...
consider a parallelogram abcd as shown below as seen, the diagonals bd and ca bisect each otherat the point o. o is the midpoint of bd, hence od = ob similarly, o is the midpoint of ac, hence oc = oa in △ abc, as oc = oa, ob is the median of △ abc, therefore, the ...
From Class 10 Maths Chapter 13 Statistics Exercise 13.2, the mode of grouped data is the value that appears most frequently within a data set. In Exercise 13.2, it is calculated using the formula Mode = $L+\left ( \frac{f_{1}-f_{0}}{2f_{1}-f_{0}-f_{2}} \right )\times h...

fit. Using the fit statistics eliminated many potential models and provided some general clues as to why certain models were having trouble. After exploring the contributions to the G2and Pearson chi-squared test statistics for two models, the addition of another latent class proved very important...
