Calculate the mean‚ median‚ and mode for your data as a whole. 8. Now calculate the mean‚ median‚ and mode of each of your classes or groups. 9. Indicate which measure of central tendency best describes your data and why. Then compare your results for each class or group‚ and point out any interesting results or unusual

| The mean is the average of all of the numbers added together and divided by the number of data. The median is the middle number in a data set that is numerically in order. The mode is the number that occurs the most often in a data set. A skewed distribution measures lack of similarity in a bell-shaped graph known as a bell curve. It occurs when data is plotted on the graph based on normal measured traits.

What are the modes of acceptance recognised under the Contracts Act 1950 (Revised 1974) and common law. Support your answers with reference to decided cases. An acceptance must be communicated for it to be effective and valid. The mental assent of both parties is not required but the external manifestation should exist. The acceptor must dos something in order to notify his acceptance. For example‚ he should communicate his acceptance of the offeror. This can be illustrated

and mode. Mean is “a measure of central tendency that offers a general picture of data without inundating one with each of the observations in a data set” (Sekaran‚ p. 396‚ para 3). A more common term for mean is average. The median is “the central item in a group of observations when they are arrayed in ascending or descending order” (Sekaran‚ p. 396‚ para 5). Mode is the “most frequently occurring phenomenon” (Sekaran‚ 396‚ para 6). The following table shows the mean‚ median‚ and mode for

1. In a poll‚ respondents were asked whether they had ever been in a car accident. 157 respondents indicated that they had been in a car accident and 117 respondents said that they had not been in a car accident. If one of these respondents is randomly selected‚ what is the probability of getting someone who has been in a car accident? 157+117=274/157=1.74 2.

The yaxis on Orthotics and Prosthetics’ graph has been altered to have a larger range than the range used for the yaxis on Prosthetic‚ Inc.’s graph. If the same range was used for both graphs‚ they would look as follows: Example 2: ABC.com presented that the average blood sugar level before meals for Americans is 142 mg/dL

Measures of Central Tendency 1. What Do You Mean by Mean? a) The mean of the salaries is calculated by adding up each individual salary and dividing it by the seven employees. The mean of the seven salaries is $43‚814.29. The mean compares to the individual salaries because it shows the average of all the salaries together. The employees would use the average to negotiate with Dick for a higher salary‚ because by looking at the average you can see that Dick’s salary is an outlier compared to
