What are the limitations of descriptive statistics? Descriptive statistics are limited in so much that they only allow you to make summations about the people or objects that you have actually measured. You cannot use the data you have collected to generalize to other people or objects (i.e., using data from a sample to infer […]
What are three differences between a spreadsheet and a database?
What are three differences between a spreadsheet and a database? Difference between Spreadsheet and Database : Spreadsheet Database It is an interactive computer application for organization, analysis and storage of data in tabular form. It is an organized collection of data generally stored and accessed electronically from a computer system. It stores less data. It […]
Does compressing a gas heat it up?
Does compressing a gas heat it up? Compressing air does not necessarily heat it up. For example, if the compression happens very slowly and the container is a good heat conductor, the temperature of the gas remains a constant. However, if the container is perfectly insulated or the process happens very rapidly, the temperature of […]
What are three ways the periodic table is organized?
What are three ways the periodic table is organized? Periodic table is organized by their valence electrons, atomic number and their atomic mass ( and also their reactivity/ groups and families). Periodic table lists their elemental symbol, atomic mass and their name. What are 4 ways the periodic table is organized? The periodic table of […]
What electromagnetic wave is harmful to humans?
What electromagnetic wave is harmful to humans? Extreme ultraviolet and higher frequencies, such as X-rays or gamma rays are ionizing, and these pose their own special hazards: see radiation poisoning. The most common health hazard of radiation is sunburn, which causes between approximately 100,000 and 1 million new skin cancers annually in the United States. […]
What are the three steps of inductive reasoning?
What are the three steps of inductive reasoning? Generalizing and Making Conjectures First, observe the figures, looking for similarities and differences. Next, generalize these observations. Then, we form a conjecture. Finally, in some situations, we can apply your conjecture to make a prediction about the next few figures. What are some examples of inductive and […]
When did the first era end?
When did the first era end? The conflict leads to the Empire’s dissolution as its territories in Morrowind, High Rock, and Cyrodiil break away. The war ends in 1E 420 with the Pact of Chieftains. What determines an era? An era is a span of time defined for the purposes of chronology or historiography, as […]
What is the most resistive force?
What is the most resistive force? Friction is the most common resistive force. A freely moving object can be slowed down and even stopped by a resistance. The rate of acceleration of an pushed object can be reduced by a resistive force. Is weight a resistive force? Weight Weight is a force caused (on Earth) […]
Why is excess supply bad?
Why is excess supply bad? When the supply is less than demand, there will be shortage of goods and services. Therefore, the demand for it increases. Everything in excess is called excess capacity and it is not good for the industry and the market. Is supply and demand always true? The supply and demand model […]
Why is determination of melting point useful?
Why is determination of melting point useful? Melting points are often used to characterize organic and inorganic crystalline compounds and to ascertain their purity. Pure substances melt at a sharp, highly-defined temperature (very small temperature range of 0.5 – 1 °C) whereas impure, contaminated substances generally exhibit a large melting interval. Why do impurities affect […]
