Echo is the Roman name. It was transliterated (when you replace the Greek sounds with their equivalent Latin letters) from the Greek Ἠχώ. It's similar to how the Greek and Latin words for Apollo are the same, just that the Greek is spelled using the Greek alphabet. Sometimes the Romans didn't have original equivalents, so they just used the Greek name.
The Greek people and those who want to learn Greek.
the drachma was an ancient Greek coin. Now, the Euro is used as Greek currency.
Pandora is indeed her Greek name. In Greek, it is written Πανδώρα
Both spellings can be used, though Kronos is more "Greek".
information can be used in statistics is known as ( 3 letters)
There are loads of them. The ten numerals: 0, 1, 2, 3, ... 9. Letters of the Roman and Greek alphabets are used to represent variables or parameters in algebra or statistics as well as geometric forms. +, -, * and / are the symbols for basic arithmetic operations but there are symbols for summations, differentiation, integration.
Will a sample descriptive statistics accurately estimate the underlying population's parameters?
The parameters of the underlying distribution, plus the standard error of observation.
I'll give you some common Greek symbols used in statistical analyses. I can't tell you which is the most common one given the enormous task of reviewing every statistics book. The Greek mu for mean, sigma for variance and rho for correlation are probably the first ones that one encounters in statistical analyses. Also, beta for beta distribution, gamma for gamma distribution, chi for chi-squared distribution. Alpha and beta are common as distribution parameters. In derivations, delta is common for differences of variables. Tau is common for a time variable. You will find more information in the related link.
They give estimates of unknown parameters which can then be used to make predictions based on distributions which are better known.
There are no weird letters in maths. Greek mathematicians were responsible for a significant amount of the early mathematical work and they, naturally used Greek letters. Many of these letters are still used today. Just because you are not familiar with characters in the Greek alphabet does not make them "weird letters".
There are several different parameters one can use for measuring various statistics about paging and swapping. -S, -W, and -B are all related and display slightly different statistics.
Yes, English and Greek characters (letters) are the most frequently used symbols for variables.
Parameter is any attribute Statistic are the measured values of a parameter. A statistic is a sample value such as the average height of a group of students. A parameter is a functional constant such as the mean of a normal distribution. Statistics are often used to estimate parameters. For instance, a sample average is an estimate of the mean.
The abbreviation for nanometer is "nm". No Greek letters are used in this case.
Greek letters in options or what are known as Options Greeks are the mathematical parameters used in pricing an option and to determine the characteristics of an option. The greek letters are:1. Delta : sensitivity of an option's price to changes in the price of the underlying asset.2. Gamma : rate of change of an option's delta to changes in moneyness.3. Theta : rate of decay of premium per day4. Rho : sensitivity of an option's price to changes in risk free interest rate5. Vega : sensitivity of an option's price to changes in implied volatility
