What are the next 2 numbers to this sequence 3354435?
The repeated digit for each pair of numbers increases by 1 with another number in between each pair.So we have 33?44?55?.The number in between each pair decreases by 2 at each stage335443551The next two numbers are therefore 5 and 1.
What is correlation What are the different types of correlation Why is it important to determine correlation What does it mean when it is said that two variables have no correlation?
A correlation is the relationship between two or more variables. Correlations are described as either weak or strong, and positive or negative. There can be a perfect correlation between variables, or no correlation between variables. It is important to determine the correlation between variables in order to know if and how closely changes in one variable are reflected by changes in another variable. This is done by determining the coefficient of correlation (r), which describes the strength of the relationship between variables and the direction. -1 ≤ r ≤ +1 if r= +1 or -1, there is a perfect correlation if r= 0 there is no correlation between the variables. a value closer to + or - 1 demonstrates a strong correlation, while a value closer to 0 demonstrates a weak correlation. a + value demonstrates that when one variable increases the other variable increases, while a - value demonstrates that when one variable increases the other variable decreases. However, it is very important to understand that correlation is not the same as relationship. Consider the two variables, x and y such that y = x2 where x lies between -a and +a. There is a clear and well-defined relationship between x and y, but the correlation coefficient r is 0. This is true of any pair of variables whose graph is symmetric about one axis. Conversely, a high correlation coefficient does not mean a strong relationship - at least, not a strong causal relationship. There is pretty strong correlation between my age and [the log of] the number of television sets in the world. That is not because TV makes me grow old nor that my ageing produces TVs. The reason is that both variables are related to the passage of time.
Inversely Proportional indirect Some things are not always directly proportional. If as one fact increases another number fact decreases at a constant rate then the numbers are said to be inversely pr?
if two same charg are bring to each other in some force they are repell,it is called inversely propotional.it is true or not?give a correect answer
What exists when one variable depends on the square of another?
Quadratic Relationship
Why cant correlational studies show causality between two variables?
Correlation can only show that one variable increases linearly as another increases or decreases. It cannot show non-linear relationships. There can, therefore, be a perfect non-linear relationship and the correlation coefficient can be zero. For example y = x2 in the range (-a, a) for any positive number a, Second, correlation cannot determine whether A causes B or B causes A. There is probably a good correlation between my age over the last 10 years and the number of white hairs on my head. However, I do not think that white hairs caused me to GROW older (I may look older, but that is another matter entirely). Furthermore, when there are two correlated variable, there may not be any causal relationship between the two variables but there may be a third variable that causes both. There is a fairly good correlation between my age and the number of cars in the UK. My growing old did not increase the number of cars and the number of cars did not make me grow old. So there is no causal relation between them. Instead, both are correlated to time.
What is an anticorrelation?
An anticorrelation is a negative correlation, a relationship in which one value increases as another decreases.
What relationship occurs between prey and another organism?
predator kills and eats prey for its survival. When the predator population increases, the prey population decreases because of too many hunters. When the prey population decreases, the predator population decreases because of the lack of food. Then, the prey population increases because there aren't that many predators and the process repeats itself.
What is a re-dox reaction?
A reaction in which electrons have been transferred from one atom to another .
When a piece of copper and another of germanium are cooled from room temperature to 800 K then the resistance?
Each of them increases
What happen to atoms in an oxidation-reduction reaction?
The oxidation state of one atom increases while another decreases.
What happens to atoms in a oxidation reduction reaction?
The oxidation state of one atom increases while another decreases.
What is the meaning of inverse and direct relationship?
An inversely proportional relationship shows that as one variable of an equation increases, the other will decrease. A directly proportional relationship shows that as one variable increases, the other increases as well.
What happens to atoms in an oxidation-reduction reaction?
The oxidation state of one atom increases while another decreases.
What happens to atoms in an oxidation - reduction reaction?
The oxidation state of one atom increases while another decreases.
What amount of energy dreseases?
Total energy is always conserved. However, it is possible to convert one type of energy to another. With some limitations, you can usually convert many types of energy to many other types. Whenever this happens, the amount of one type of energy decreases, while the amount of another energy increases. For example: if an object falls down, its potential energy decreases; its kinetic energy increases. Once it crashes to the floor, its kinetic energy is converted into heat - in other words, kinetic energy decreases, while heat energy increases.
What describes a situation in which one event happened directly because of another event?
Casual Relationship, APEX
What is a mathematical relationship?
In a linear relationship such as represented in the equation x= b+ay. The relationship between the x and y is a direct variation. This basically means that in the above equation/situation the value of the y variable is proportional to the value of the x variable. In other words the x and y increase or decrease proportionately. If the x value decreases the y value decreases. If the x value increases so does the y value. Now in a quadratic relationship it is a little different in that this kind of function is actually in the shape of a parabola. The equation for this relationship is ax2 + bx + c = y. The parabolic relationship exists when one variable depends on the square of another and this relationship is often expressed in saying that the y variable varies directly with the square of the x variable.
