Which measure of central tendency mean mode median is used for IQ?
The mean.
Who invented mean median and mode?
i do not knowDon't Listen to this idiot, because the person who typed in this answer is obviously stupid. Mean, median and mode have been used countless of times. No one really knows who invented them or mathematics.
Is rather than a preposition or a conjunction?
The pair together may be either.Than is a preposition. It isn't used to join two statements that could each be a sentence in their own rights. Rather is an adverb that must be followed by than; it says that it would be preferable for you to do the first option than the second and has the same effect when put before rather as when put after the verb. So rather than followed by a noun can be a preposition meaning "instead of" (e.g. potatoes rather than rice, stayed rather than going home).However, the pair "rather than" can also connect an infinitive clause (rather than a gerund), acting as a conjunction as in the example,"Rather than continue the argument, he walked away."
Mean median and mode are always equal?
The mean, median, and mode are not always equal. For example, consider the set of 5 values {2, 3, 5, 10, 10}. The arithmetic mean is 6. (The values sum to 30, and 30 divided by 5 is 6.) The median is 5. (The middle number of the 5 values, when sorted, is 5.) The mode is 10. (The value 10 appears most often in the set.) And, you probably didn't ask, but: The geometric mean is the fifth root of 3000, or about 4.96. The harmonic mean is 150 divided by 37, or about 4.05. The quadratic mean is the square root of 47.6, or about 6.9. Although the word "average" can technically be used to describe all of these values, in common parlance the word "average" refers to just the arithmetic mean.
What is the average for 4 and 10?
There are 4 types of average that are commonly used: Mean, Mode, Median and Range. The Mean is all values added divided by number of values. In the case 4+10/2 = 7 The Mode is the most frequently occurring value. In this case there is no mode The Median is the middle value of all of the values. In this case the answer is 7 The range is the highest value minus the smallest value. In this case 10-4 = 6 Ajcollin
