When there are an equal number of values, the mid-point between the two central values is the median.

Mathematics Cognitive Domains–Fourth and Eighth Grades

For example, if the prices of seven sandwiches bought on campus are placed in order the median will be the 4th price in the sequence:. When the six starting salaries from example 2 are placed in order of magnitude the median value lies half-way between the 3rd and 4th salaries:. The median is a good measure of the average value when the data include exceptionally high or low values because these have little influence on the outcome.

The median is also easy to calculate but this does not imply that it is an inferior measure to the mean — what is important is to use an appropriate measure to determine the average. Another area where the median is useful is with frequency data. Frequency data give the numbers of people or things in particular categories.

For example, the frequency distribution of shoe sizes for a sample of 21 women was collected and is summarised in table 3. A common mistake is to think that the median shoe size is 6 since this is the middle value in the first column. This is incorrect since it is the frequency information rather than the category shoe size that must be considered. The 11th value in the frequency column corresponds with a shoe size of 5.

Range (statistics)

An alternative way of finding the median shoe size in this case is to re-write the data from the table to show each shoe size and the number of times it occurred in each category and use this to work out the median:. The mode is the value that occurs with the greatest frequency in a dataset. It is representative or typical because it is the most common value. There may be more than one mode in a dataset if several values are equally common; alternatively there may be no mode. In example 3 frequency distribution of shoe sizes , size 6 is the mode or modal class , since this shoe size occurs the most frequently 7 times in the sample.

The mode is the only measure of average that can be used with nominal data. No median or mean can be calculated but the mode is biological science students as students from this faculty were the most common. In addition to the manual methods described above, you can also calculate the mean, median and mode in Excel using special commands. The corresponding cells in the spreadsheet show the result of the calculation. Example 4, below shows how Excel can be used to find the mean, median and mode of the student loan data originally given in example 1.

Column A shows the different categories of student, whilst column B shows the amounts borrowed. Well the African American students brought up a good point. They asked how many jobs the person is working whereas the dominant culture probably assumed. Philosophy of Mathematics A philosophy of mathematics should be included in an excellent philosophy of education.

Each of these ideas should forever be evolving because. Teaching mathematics has evolved from the traditional instrumentalist view where the focus is on knowledge mathematical facts, rules and methods as independent concepts, to the more contemporary constructivist approach which focuses on building on prior knowledge and experiences incorporating mathematical facts, rules and methods to problem solve and investigate new mathematical concepts.

This will in turn, enable students to apply concepts in real life situations. Teaching thematically is an approach. Mathematics is possibly one of the most underappreciated sciences. It everywhere in our lives, mathematics runs our computers, flies our aircraft, and protects our information.

But for such a major part of our lives, very few people can say that they know how it is done, how the RSA encryption protects their e-mail, or even that 21 squared is without going into tedious mental calculations or reaching for their calculator. Contrary to popular belief, mathematics has a wide range of useful applications. Those who would ask whenever they would need algebra, both linear algebra and calculus is used extensively in computer programming and engineering.

The fact is that mathematics is integrated into almost every profession, and every …show more content…. There are some issues with this system. For example, imagine that both Person A and Person B want to include a third person in their correspondences, Person C.

First they would need to give Person C a key, through some sort of secure system, preferably a face-to-face meeting. This is a key weakness of the symmetric key system. In an asymmetric key system, Person A sends many open locks to Person B, these locks can be put on messages and only Person A has the key to them.
