How many peaks would you expect for the distribution of the results of rolling a fair die 1000 times?

With 1000 rolls of a die, and each number having a probability of 1/6, I would not expect any peaks.

Is considerably skewed distribution the same as bimodal distribution?
No. A distribution may be non-skewed and bimodal or skewed and bimodal. Bimodal means that the distribution has two modes, or two local maxima on the curve. Visually, one can see two peaks on the distribution curve. Mixture problems (combination of two random variables with different modes) can produce bimodal curves. See: http://en.wikipedia.org/wiki/Bimodal_distribution A distribution is skewed when the mean and median are different values. A distribution is negatively skewed when the mean is less than the median and positively skewed if the mean is greater than the median. See: http://en.wikipedia.org/wiki/Skewness
How is frequency distribution useful to us?
I suspect you are referring to a sample frequency distribution.Providing that the sample size is sufficiently large there are various kinds of information that can be gleaned from one:the approximate range of values in the populationthe location of the population as measured by the value that appears most often in the frequency distribution-known as its modethe likely shape of the population's distribution, in particular whether it is symmetric or skewedobviously how values of the population variable are distributedwhether there are any curious peaks or valleys, even when the sample size is largethe amount of variation around the central value
What is the difference between a histogram and a bar graph?
a histogram has intervals a bar graph does notAnswerA histogram has all the bars smooshed together while a bar graph has them apart. A bit more detail:A histogram looks sort of like mountains, valleys, and peaks. It goes up and down, depending on how the numbers change, with no break in between. A bar graph has columns which are straight up and down, with breaks (spaces) in between the columns.
What is the significance of a bell curve?
When you are graphing some quantity, in many cases you will wind up with a curve that is shaped like a bell, in other words, the graph gradually rises, then rises more sharply, then flattens out and declines in a symmetrical pattern, the same way that it rose. This reflects the fact that a great many things have a normal range, and so the quantity of that item peaks in the normal range and then declines as you get either more or less than the peak, and furthermore, the pattern does tend to form that distinctive bell shape. You could, for example, do a chart of the annual income of American families. Some have very high income, some have very low income, and most fall in the intermediate range. But you could do the same thing with endless numbers of other topics. If you were to capture pigeons and make accurate measurements of the lengths of their beaks, and then graph the results, you would get a bell curve. You could graph the weight of pet cats, or the cost of sweaters, or the age of houses, and so forth. Most things will produce some kind of bell curve.
Does symmetrical distribution have multiple peaks?
It can have multiple peaks, but most symmetrical distributions do not.
What is the maximum peaks that investigators would expect from Y-STR?
The maximum peaks that investigators would expect from y-str would be three to eight peaks
What are curves called that have two peaks?
In statistics, a distribution curve that has two peaks is referred to as bimodal.
A type of selection where the normal distribution is pushed apart into two separate peaks?

Does a symmetrical distribution have a variation?
Yes. The distribution can be compact (centred tightly around the mean) or spread out. It can have a peak in the centre or two peaks at each end, or other variations.
Show that probability of finding particle in harmonic oscillator is maximum at extreme?
The particle moves much slower at the extremes than at the middle and therefore it spends more time there. Peeking randomly we can certainly expect to see it at extremes because of that. More rigorously, the derivative of the sine is the cosine. This means that the slope of the sine is +1 or -1 at the axis crossing, 0 at the peak, and between +1 and -1 everywhere in between. If you were to accumulate a distribution curve as a function of time, pigeonholing the results based on some delta y, you would see more observations at the peaks than anywhere else because, as previously stated, the particle moves slower at the peaks.
What is theAverage IQ of Canadians?
The average IQ of Canadians is around 100, which is considered to be the global average IQ score. It is important to note that IQ scores can vary and are influenced by various factors.
How do mountains and valleys on the ocean floor compare to those on land?
They are the same because they both have water on some parts of the land and they both are a part of land on this earth. I hope this gave you a couple answers you are welcome. ~Alanna Lynn Harwick 4/18/13
