What is central tendency?
Though mean, median, and mode is central tendency, it is hard to put this into words.For an example:Your average grade in math class is an A. Though, how did you calculate that average? Well, since average means mean, you calculated that average using the method of central tendency, or in this situation, you found the mean.In other words, central tendency is just a method (mean, median and mode) to find the average, middle, and most occurring score or number in a set of data.I hope this helped! ;D~Lovingless
How do you find the measures of a central angle?
If three central angles measures 65, 87, and 112, find the measure of the fourth central angle.
Is range a measure of central location?
No, it isn't. Mean, median, and mode are the three most common measures of central location (although there are others). These measures of central location are attempts to find the middle value of a range.
How do you find a mode if 2 numbers appear the same number of times?
There are two modes. The mode is the only measure of central tendency where you can have no mode (no number appears more than another), one mode, or several modes, such as in your case.
What is the difference between median and mean value?
The Median and Mean are both measures of the central tendency or average of a group of numbers. The Median is the middle number of set of numbers arranged in ascending order. If there are an even amount of numbers, find the mean of the middle 2 values. For example the median of 6, 3, 9, 2, 12, 3, 54 is 6, determined by arranging the numbers in the following sequence: 2, 3, 3, 6, 9, 12, 54. The mean is determined by adding up all the numbers and dividing by the number of numbers. So for the example above, the sum of 2+3+3+6+9+12+54 = 89 Divide 89 by 7 = 12.7 So the mean - often called simple average is 12.7 The mean is most often used to find an average.
