What does a correlation coefficient of 0.8 mean?
It means that there is a strong positive association between changes in the two variables being studied. Positive association means that the two variables tend to increase together or decrease together. Note that there is no mention of a causal relationship between the variables.
Event 2 has a causal relationship with Event 1 when?
Event 1 makes Event 2 happen.
Linear regression r square?
r square is a measure of the linear relationship between the variables. The nearer r squared is to one, the stronger the linear relationship. However, a linear relatinship is NOT a causal relationship. Also the absence of a large r square is not evidence of no relationship: there may well be a non-linear relationship. It is commonly accepted that for scientific purposes, a very minimum of 0.98 is accepted for r2. This is because 0.98 actually allows for quite a variance (by eye)
What events are correlated but do not necessarily have a causal relationship?
A Teacher drops A box of chalk, and her chalkboard Crack a few minuets later.
What events are correlated but do not necessarily have causal relationship?
You did not list any events.
Do you get cancer if you do protest?
There is no causal relationship between protest and cancer.
Can you do well in physics and engineering if you are good at math economics and scale calculations?
Of course. You can also do poorly. There is no positive " If - Then " causal relationship between those aspirations and those talents.

What is causal order?
The term "causal order" can be defined as a method of organising ones speech to ensure that the major points demonstrate a relationship between the cause and its effect.
What does a relationship between two correlated variables have?
Correlation between two variables implies a linear relationship between them. The existence of correlation implies no causal relationship: the two could be causally related to a third variable. For example, my age is correlated with the number of TV sets in the UK but obviously there is no causal link between them - they are both linked to time.
What is the Difference between causal and anti causal signal?
a signal which has the value starting from t=0 to +ve time axis is called causal signal while , anti causal is a fliped version of causal signal i.e on -ve time axi's signal is called anti causal. ans by: 43805 The THUNDER A.A.T
In the trial of a homicide offense the prosecution must prove a causal relationship between the defendant's wrongful act and the victim's death?
True
Does a negative correlation coefficient indicate an inverse relationship?
Yes, but the relationship need not be causal.
Difference between a causal relationship and correlation?
Things may be correlated without causal relationship or conversely. Consider the Modulus function - that is the value of a number without regard to its sign. Over any domain (-a,a), there is a very strict relationship between x and mod(x), but their correlation is 0. Conversely, I expect that there is a good correlation between my age and the number of TV sets in the world. That is not to say that my getting older is producing more TVs or that TV production is causing me to age. Simply that both of them are correlated to a third variable - time. There can be correlation without such a third variable but, offhand, I cannot think of an example.
What do line plots measure?
Usually all they do is show the values of two continuous variables for a set of values. There may or may not be a relationship between the two variables. If there is, it may or may not be a causal relationship. It does not have to be a linear relationship or even a relationship that maintains its characteristic.
Which events are correlated but do not necessarily have a casual relationship?
One example of events that are correlated but do not have a causal relationship is the rise in ice cream sales and drownings. While both events may peak during summer months, there is no direct link between them causing one another. Another example is the correlation between the amount of TVs sold and the number of births in a population, which are linked to economic and societal factors rather than a direct causal relationship.
Which research method is most appropriate if you are looking for a causal relationship?
experimental method
