Meaning of Centralized Data Mean, Median and Modus Data Center Meaning, Median and Modus Size - A centralized measure of a group of data is a value or data that can represent a group of data or often referred to as averages. The average value in general has a tendency to lie in the middle position within a group of data arranged in sequence or in other words has a tendency to center. An example of a height data from some students is as follows: 135 140 150 150 155 155 157 160 From the data it is seen that a large proportion of the student's height can be estimated at about 150 cm. Thus, it can be deduced that 150 is a centralized measure of the student's height data above. You need to know that there are several types of data centering sizes commonly used in mathematics namely Mean, Median, and Modus. In this article The Basic Mathematical Formula will explain it one by one at the start of Mean. [194590] The Measures of Central Data Mean, Median and Mode Mean / Abbreviate Count ] Referred to as the mean of a set of data is the total sum of the data divided by the number of available data. If it consists of n ie x 1 x 2 x 3 ... x n then the mean of the data can be formulated as follows: ]

Modes

In a process of collecting data, it will usually get mixed results. There is data that appears only once da tone also data that appears many times. The most commonly emerging data is called the Mode.
[194590]]
Sample Problem and Solution:
Find the mode of the following data:
a. 4, 6, 5, 7, 5, 8, 5, 6, 7
b. 1, 3, 2, 4, 2, 3, 5
c. 1, 10, 7, 8, 4, 3, 5, 9

Completion:
a. Number 5 appears 3 times on the data, then the mode is 5
b. Numbers 2 and 3 have the same frequency (appears 2 times) then the mode of the data is 2 and 3. The two-mode data is referred to as bimodus .
c. Because each data has the same frequency then there is no mode.


Such is the explanation and discussion that can be given by us about Measures of Central Data Mean, Median and Mode hopefully can help you To better understand this material.

Units of Size The number of Lusin, Gross, Rim, and Kodi

Unit Size The Number of Lusin, Gross, Rim, And Kodi - When carrying out your daily activities you must have heard some terms like Lusin, Gross, Rim, and Kodi in mathematics the term is called a unit of measure of quantity or quantity. This unit is commonly used to express the number of items or objects. For those of you who do not know or have not memorized by the size of the unit, let us study it together by listening to the discussion The Basic Mathematical Formula on the following unit size sums: The most commonly used unit of measure quantities is : 1 dozen = 12 pieces 1 gross = 144 pieces = 12 Lusin 1 score = 20 pieces ] 1 rim = 500 glue Bar The use of units of measure of the number of Lusin, Gross, Rim, and Kodi The above sizes are usually used in accordance with certain types of goods, for example: Lusin The term dozen is more often used to express the number of items such as glasses, plates, spoons, jars, and so on.

Have you already read posts Mathematical Formulas Dasa r regarding How to Calculate Distance point to point, Line, and field ? if not, you should read it first so that you can more easily understand Sample Questions and Discussion How to Calculate Distance Point to Line In Cube which will be described below: Sample Questions and Discussion How to Calculate Distance point to Line In Cube Example Problem 1 Unknown length ABCD.EFGH ribs cube is 6cm. Then calculate the distance: a) .period D to line BF b) .period B to line EG Solved: a ) .Agar easier to answer that, let us look at the picture below: From the above picture we can see that the distance of the point D to the length of the diagonal line BD BF is to be determined by using Teor ema Pythagoras or formula. Let's finish with the theorem of Pythagoras first: BD2 = AB 2 + AD 2 BD2 = 6 2 + 6 2 BD2 = 72 BD = √72 = 6√2 cm beikut if we look for it by using the formula: d = s...

Example Problem Arithmetic Social About Discount / Rebate

Example Problem Arithmetic Social About Discount / Rebate - the meaning of rebates are rebates granted to a product or service. We are more familiar with rebates as a discount. You'll often see at the supermarket or supermarket there are a lot of rebates or discounts, it is an example of a rebate. If you are curious about how to calculate the price cuts, the Mathematical Formulas Basic will give his review to you through examples to the following: Example Problem Discussion and Arithmetic Social About Rabat Example Problem 1 Melly want to buy a dress for Rp 120,000. It turned out that the clothes receive a rebate of 20%. What is the size of the rebate? Answer: clothes Price: Rp 120,000 Rabat: 20% x 120,000 = 20/100 x 120,000 = 24,000 Thus, rabatnya amounted Rp.24.000 Example Problem 2 [1945901million] A Shop, gives a 5% discount for every purchase math book. If a math book has a price of Rp. 85,000. what is the price of the book after the discount?...
