What does it mean to have a normal distribution of data?
The Normal or Gaussian distribution is a probability distribution which depends on two parameters: the mean and the variance (or standard deviation). In may real life situations measurements are found to be approximately normal. Furthermore, even if the underlying distribution of a variable is not normal, the mean of a number of repeated observations of the variable will approximate the normal distribution.The term "approximate" is important because, although the heights of adult males (for example) appear to be normally distributed, the true normal distribution must allow negative heights whereas that is not physically possible!
Is it true or false that The area under a normal distribution curve is always positive even if the z value is negative?
It is true. Because the normal distribution is above the horizontal axis for all values, the area under it is a positive quantity no matter the z value.
Does a sample statistic always have a normal distribution?
No, many sample statistics do not have a normal distribution. In most cases order statistics, such as the minimum or the maximum, are not normally distributed, even when the underlying data themselves have a common normal distribution. The geometric mean (for positive-valued data) almost never has a normal distribution. Practically important statistics, including the chi-square statistic, the F-statistic, and the R-squared statistic of regression, do not have normal distributions. Typically, the normal distribution arises as a good approximation when the sample statistic acts like the independent sum of variables none of whose variances dominates the total variance: this is a loose statement of the Central Limit Theorem. A sample sum and mean, when the elements of the sample are independently obtained, will therefore often be approximately normally distributed provided the sample is large enough.

What is the Average weight of a man Y Y years old?
There is no way to answer this question. First, we have no idea what YY years even means. Second, weight has nothing to do with age. Weight is based on your size, body mass, and amount of fat vs. muscle in your body.

Is it normal for your period to be irregular in the first two years?
Yes, it's normal for your periods to be irregular in the first two years and even going into your early twenties. This is because it takes time for your body to reach a point where it is mature enough to ovulate regularly, and for hormones to regulate themselves to bring about a regular cycle.

Yes. Nowadays girls are getting their periods earlier. I am ten years old and just recently got my period last July.

So, yes, it is normal for a 10 year old to get her period.

If you have pcos can your period be back to normal during pregnancy?
Hello I can relate to you, I have had PCOS for two years. I have had very heavy periods, missed periods and painfully periods for years without knowing why. I was diagnosed with PCOS a few years ago and was told that I should take bill control pills to get a "normal period" but what I wasn't told was the birth control pills do not treat the real problem which is insuline resistance. Weight gain, facial hair, depression, irregular periods and even liver disease are all due to insuline resistance and unless you treat the underlying problem it could get worst. I started an all natural system six months ago and it changed my life...please read up on it for yourself. I have had a normal period, weight loss and much more. please read for yourself on www.insulitelabs.com I hope this helps you.
Is it normal to have Heavy periods every 28 days for 5 days every month?
Yes, that can be normal. Periods average 3-5 days in duration and cycles average 28 days. But, if your periods are so heavy that they become a nuisance, such as having to change your tampon/pad every two hours or even less, you might want to mention this to your doctor if this is the case.

If you stopped taking Depo-Provera 4 months ago and started your first period is it normal for it to last 2 weeks and have a brownish color?
Yes. I was on Depo for approximately 10 years with NO period and then to the pill for about a year with controlled periods. I have since stopped taking ANY type of birth control and have had long 2 week periods and even two full periods a month. It will eventually regulate if not ask Dr. about Provera.
