The claim has been made that the mean and the standard deviation are the most important measures of location and dispersion in statistics. Some commentators claim that these measures are more important than other measures such as median, mode or mean deviation. QUESTIONS: Why the emphasis on mean and standard deviation ra
I need an XY scatter graph using Microsoft Excel that has 30 for a maximum y axis and 4 for a maximum X axis. The numbers on the x-axis are offset with the numbers 0, 2, and 4 on the lines. The entire graph must have 36 individual cells. The graph needs to show all of the numbers 0-4, but only 0, 2, and 4 are directly on a li

What are the main differences between descriptive and inferential statistics? Give examples of each. When would random sampling not be the best approach to sample selection? Give an example.
SS within samples is a sum of squares representing the variation that is assumed to be common to all the populations being considered. Is this true? Explain
1. Test the claim that the samples come from populations with the same mean. Assume that the populations are normally distributed with the same variance.

A completely randomized (CRD) experiment was conducted in a glasshouse to test whether mature sugar beet roots are heavier when using a new fertilizer (A). Twenty pots of equal size were filled with the same compost and randomly placed on the bench in two parallel rows as shown below. To ten of pots the old fertilizer (B) was ad
6. A widely-used value function to represent the value of total assets to an individual is the natural logarithm of the assets; this means that the value of total assets of amount X is proportional to ln (X) (the natural logarithm of X). This value function is sometimes referred to in economics as the "decreasing marginal utili
