what is a central tendency in math?
481507
I think this is about asking people to rate things on a scale, for example "How much do you like eating cheese? rate this on a scale of 1-10 where 1 means "I hate cheese, I wouldn't eat it if you paid me twice my annual salary" and 10 means "I love cheese, I want to eat it all day."" Irrespective of what they actually think, most people will opt for a number roughly in the middle of the scale, so you will get lots of 5's and 6's and very few 1's or 10's. this means the results from this kind of question may not be accurate.

It's a real "use-it-or-lose-it" skill, but most people find that their major problem in mathematics is a poor understanding of the basic ideas. And I do mean basic! Math is a harsh mistress, and those small 'easy' mistakes often trip people over more than larger problems! So take a crack at any problem areas you KNOW you have and stuff, stuff, stuff your brains with it!

Sure you have learned it. It's addition. If the mean (average) must be in the middle (the third number) then the numbers are:\n\n15,16,17,18,19\n\nand sum is 5*17 or 85

The arithmetic mean is the average or the sum of the data divided by the sample size.  It is an appropriate measure of central tendancy for data taken for a normal population.  505 of the data is on one side of the mean and 50% on the other (Bell shaped curve).  In this case, the mean equals the median.  \n\nThe median is the exact middle of the data by count.  Splits the data by count not value.  (If you had 9 data points the median would be the 5th number when order from smallest to highest.)  It is a good measure of central tendency for skewed data or data with long tails.  Nonnormal.  For highly skewed data, the mean and median could be far apart.\n\nMode is the most frequent value in the data set.  It is good for central tendency for data with multiple modes (bimodal, trimodal, etc).  It is also good for nominal data (nonnumeric data).

c) geometric.  Every term is 1/2 of the prior term.  The ratio is 1/2.

Standard deviation tells you how spread out a set of numbers is.  A small standard deviation means that the numbers are close together.  A large one says that they're far apart.\n\nIt's often used as a measure of distance away from the mean.  In a normal distribution, about 68% of numbers are within one standard deviation from the mean.  For example, if you have a normal distribution with a mean of 50 and a standard dev of 10, then about 68% of the numbers are between 40 and 60.  And about 95% of the numbers are within two standard deviations, or between 30 and 70.

Math, math and math. Modern mainstream Economics is basically an aplied math course. If you get the math part, the concepts are fairly easy.

Correlation! (Maybe... well the 6th letter is L at least).\n\nCorrelation basically describes the strength and direction of the (linear only) relationship between two variables or sets of observations. \n\nIt's a number between -1 and 1, and is denoted by 'r' or the Greek letter 'rho' (it looks like a 'p').  E.g. r = 0.87 \n\nI hope that's the kind of statistical symbols the crossword clue is referring to. \n\nGood luck with the crossword!

the mode of a set of numbers is the number that occurs most often.  for example, in the set 2, 4, 5,8, 8, 9, the mode is 8, as it occurs twice and the others only once.  another example: 7, 9, 9, 2, 5, 5, what is the mode?  there are actually two, 5 and 9, because the both occur the most.  if all numbers occur the same number of times, then there is no mode.\ncheck your math book and ask your teacher for more explanation.\nall you have to do is count the numbers, some people find that it helps to put them in order, so that they can be sure not to miss any. (instead of 7, 9, 9..., rewrite as 2, 5, 5, 7, 9, 9, this is also helpful when doing mean and median)\ngood luck on your work!  i like that you didn't include the actual problem, that shows that you really want to learn, not just take the easy way out.

Mathematics is the study of quantity, structure, space and change. It developed, through the use of abstraction and logical reasoning, from counting, calculation, measurement, and the study of the shapes and motions of physical objects.

symmetry (fold a piece of paper in half.  2 students work together.  One places a tile on his/her side, the other places his/hers on their side but both sides must be symmetrical.  Be creative to make a picture.), graphing (if they are colored or different shapes), non-standard measurement, sorting, addition/subtraction manipulatives, patterns (if colored or different shapes), discuss attributes.  Of course I teach first grade so GLE's in higher grades may be different.

There are actually many different types of "mean." The most common "mean"  is the arithmetic mean, also called the average in everyday language.\n\nCalculating the arithmetic mean is simple: Add all the values in the sample together and divide by the total number of values in the sample.\n\nThe arithmetic mean is often used to describe data. The problem is that it doesn't always necessarily give the correct picture.  Sometimes it is better to use the median, which is the number found exactly in the middle of the set of values, or the mode, which is the number most frequently reported. It depends on the data involved and the question you are asking about the data.\n\nWhat this all comes down to is: the mean is a measure of central tendency (as are the median and the mode).\n\nThe other two most common means are the geometric mean and the harmonic mean.

Calculus is a central branch of mathematics. The word stems from the nascent development of mathematics: the early Greeks used pebbles arranged in patterns to learn arithmetic and geometry, and the Latin word for "pebble" is "calculus."\n\nCalculus is built on two major complementary ideas, both of which rely critically on the concept of limits. The first is differential calculus, which is concerned with the instantaneous rate of change of quantities with respect to other quantities, or more precisely, the local behavior of functions. This can be illustrated by the slope of a function's graph. The second is integral calculus, which studies the accumulation of quantities, such as areas under a curve, linear distance traveled, or volume displaced. These two processes act inversely to each other, as shown by the fundamental theorem of calculus.\n\nExamples of typical differential calculus problems include:\n\nfinding the acceleration and velocity of a free-falling body at a particular moment. \nfinding the optimal number of units a company should produce to maximize its profit. \nExamples of integral calculus problems include:\n\nfinding areas and volumes \nfinding the amount of a liquid pumped by a pump with a set power input but varying conditions of pumping losses and pressure \nfinding the amount of parking lot plowed by a snowplow of given power with varying rates of snowfall.

That means a survey of a population of similar cases to find out what percentage of cases exhibit one characteristic versus another. It's a statistical kind of attempt to find out what the average is and how much different cases might deviate from the average case. In mathematical statistics they refer to these parameters of the population as the mean and standard deviation.

Comes from the age old bell curve of society. All societies naturally strive for civilization. This is generally where the "5%" rule came in to play. The thinkers, doers, and other leaders generally amounted to about 5% of the over all population. This generates a bell curve, pulled up in the center by the three "C's", Centralist Common sense Conservatism. Half way down the curve on the right would then be the over conservatives as half way down on the left would be the moderates. At the bottom of the curve on the right were the extreme conservatives and at the bottom left, the liberals. Half way out the right wing are the ultra conservatives, (some call them neo-cons) and half way out the left wing, the progressive liberals. The two ends are where you find the fanatics, the religious fanatics on the far right and the atheists on the far left. Over time, in most countries, the conservatives are to the right and the labor party liberals to the left. When the curve slips too far one way or the other, the society generly falls. History shows this with the early Greeks, the Romans and even the Neanderthals.
