The classification and collection of data that are in the form of numbers is called?
Statistics
Does the population size increase or decrease at higher trophic levels in the pyramid of numbers of an ecosystem consisting of any herbivores and birds feeding on the insects?
Population sizes decrease at higher trophic levels. If they increased the insects population would decrease meaning there would be less food available for the birds so their population size would then decrease. Look at the relationships between predator and prey species for more information
Why was basis of classification of element in the periodic table changed from atomic mass to atomic number?
Mendeleev's periodic table was based on the atomic masses of elements. However, this was not effective when isotopes were discovered. An isotope of an element is defined as the element having the same atomic number but varying mass numbers. So, mass numbers weren't constant and hence, a better characteristic was chosen -atomic number. Atomic number of any element was a characteristic of a particular element. Hence atomic numbers were taken as the basis of classification instead of atomic masses.
By what property did Moseley suggest that the periodic tabe be arranged?
After atomic numbers Henry Moseley supported the arrangement of periodic table of Mendeleev after atomic numbers and properties by a strong physical conception: study of the lines of X-ray spectra of chemical elements. It is a true relation between atomic numbers of elements and the wavelenghts of the characteristic X-ray lines.
What basic information is contained in the Periodic table of elements?
The periodic table include only chemical elements each has a unique atomic number that represents the number of protons in its nucleus. Most elements have differing numbers of neutrons among different atoms these are referred to as isotopes.
Do you lose or gain information when you use statistics to reduce a population to a few characteristic numbers?
you lose information!becoz you can nearly exact the data based on the charateristic numbers
What is a set of numbers representing some sort of information from the sample or population?
Statistics or data set
In statistics what is the set of numbers representing some sort of information from the sample or population?
Data Set
What are the set of numbers representing some sort of information from the sample or population?
The general term statistics might be the set of numbers representing some sort of information from a sample population. The term data set can also be applied.
What are factual numbers in an almanac?
Factual numbers in an almanac are data and statistics that are true and based on reliable sources. These numbers typically include information such as historical events, astronomical data, weather patterns, population figures, and economic indicators. Almanacs are known for providing accurate and up-to-date information for a wide range of topics.
What are the statistics for the Baltimore Ravens?
They are the numbers that detail the relevant information for each play in which the Ravens have been a participant.
The law of large numbers?
The law of large numbers states that as the number of observations in a sample increases, the sample mean will tend to approach the population mean. In other words, the larger the sample size, the more accurate the estimate of the population parameter. This law forms the basis for statistical inference and hypothesis testing.
Statistics in singular sense?
Statistics is the art of lying with numbers.
What is data and sample?
Data is commonly referred to the quantitative attributes of a variable. A data is nothing but a result of something. Through this result, the information is derived. Sometimes we refer to Raw Data which is unprocessed in nature which can mean a collection of numbers or characters that collect information and then convert from quantities to symbols. Sample, in statistics can mean a subset of a population. Population can be huge, so the sample can represent just a manageable size. Sample is first collected and then the statistics are derived from the sample. This process is known as Sampling.
What are the most frequently drawn UK lottery numbers?
The problem with this question is that as soon as you answer it the statistics change as new draws are made. By far the simplest way to get information on the most common National Lottery numbers is to follow the related link titled "Lotto Statistics"
