The Standard deviation is more useful for computing and understanding the measure of something. For example‚ if you know the standard deviation of a test given to a group of students is 5 and the average is 80‚ this tells you much more information than just having the average score. If on the other hand the standard deviation is 20 and

Dr. Williams wanted to see if the amount of television a person watched was related to that person’s depression or lack thereof. To find this out‚ Dr. Williams conducted a correlational study. A correlation is a shared relationship or connection between two or more things. A correlation can be either positive‚ negative‚ or zero. A positive correlation is when factors or variables moves directly of each other‚ meaning if one variable goes down‚ the other will as well and vice versa. A negative correlation

Results The mean attitudinal sore of all 25 respondents towards the Aaron Hernandez murder trial was 71. As can be seen in Table 2 below‚ this mean falls in the undecided category. The sample standard deviation of the scores was 11.74. The distribution of the 25 scores is seen as well. The two most frequently scored categories are undecided and unfavorable. The category with the fewest respondent is favorable. TABLE 2: Distribution of Scores Attitude Categories Score Range Frequency Very Favorable

The affect of temperature on the rate of movement of woodlice Aim: The aim of this experiment is to establish whether a change in temperature affects the rate in which woodlouse move. I measured the rate by timing the woodlouse to move a set distance of 20cm‚ and altered the surrounding temperature by submerging a clear tube in water with different temperatures controlled by a water bath. Research: It is to be believed there over 3000 different species of woodlice‚ a total of 42 species

In this assignment‚ we will explore RFM segmentation‚ a technique used to group customers according to their aggregate purchase history with a company. We specifically look at how recently customers have purchased (R – recency)‚ how often they have purchased (F – frequency)‚ and how much they have spent (M – monetary). We will then consider how these different segments responded to the offer to buy “The Art History of Florence
