Executive summary Arazindi Fashion House (AFH), an Australian clothing store, initiated a promotional technique in which customers were issued with a card that entitled them to a 20% discount on any purchase they made during the month of June. The nationwide sales manager of AFH conducted a research that was mainly intended to establish the effectiveness of this promotional technique. Particularly, the research intended to establish whether or not the amount of sales was influenced by the use of promotional cards. A sample of 200 customers was used in the research. From this sample, techniques of data analysis such as correlation, use of descriptive statistics, and graphical methods were used to answer the questions posed by the research.

Analysis of variance

The Standard Deviation is a measure of how spread out numbers are. Its symbol is???(the greek letter sigma) The formula is easy: it is the?square root?of the?Variance Variance = The average of the?squared?differences from the Mean. To calculate the variance follow these steps: Work out the Mean (the simple average of the numbers) Then for each number: subtract the Mean and square the result (the squared difference). Then work out the average of those squared differences. (Why Square?)

The secret of success is using _______________ to check each step of the operation. Consumer trials stick to a precise script so the results can be compared _______________. Any _______________ due to order of presentation gets cancelled out in the second round. There?s one more essential step, ________________________ the whole package in selected cities and measuring the response. Without these statistical analyses, we would never really be sure whether or not two things are ___________________ different or not, we?d just be guessing.

What Makes a Worm?s Heart Race? Part 1 - Learning Name: Hour: Date: Purpose: To explore the impact of treatments on the pulse rate of the worm Lumbriculus variegatus while refreshing and refining your understanding of experimental design with a focus on recognizing and minimizing experimental bias. Objectives: Upon completion of this activity, you should be able to: Count pulse rate in blackworms (Lumbriculus variegatus). Demonstrate the ability to design and perform an experiment using the strong inference model and multiple hypotheses with attention to the minimization of experimental bias. Demonstrate an understanding of graphing and the use of simple statistical data analysis to evaluate the impact of an experimental treatment.

Statistics Ch. 6 Test REVIEW Name: KEY Date: Part 1: Multiple Choice (2 points each) Here are the means and standard deviations of the weights of two groups of cats. Which statement is true? Al the cats in group B weigh less than all the cats in group A. The weights of each group follow a Normal model. A 3.3 pound cat in group B is closer to average than an 8.2 pound cat in group A. Compared to group B, the weights in group A are closer to the mean. In a Normal model, what percent of data is between -1 and +2 standard deviations of the mean? 68 81.5 99.7 It depends upon the standard deviation Normal model A has a smaller standard deviation than Normal model B. How do the graphs of these models compare when drawn on the same scale?
