5. Cause and Effect - GHCI Grade 12 Mathematics of Data Management
In this lesson, you will learn how to identify cause-and-effect relationships within a text. Let's take a look at some examples of cause-and-effect relationships. Cause and effect is a relationship between events or things, where one is the result of the other or others. YourDictionary definition and usage example. Obviously, these are extreme examples but it shows the dangers of not understanding the What is the definition of causation vs correlation.
They are not causes, and not part of the feedback loop. Applying some intervention to scrub away the symptom does not change the cause-and-effect relationships within the loop. If you scrub away the symptom, it does not cure the problem.
All it does is break the correlation, making the quantity no longer a reliable symptom. RS Latch, Multiple Inputs In this circuit, there are three different inputs that could set the latch, plus two inputs that could reset the latch. Suppose it is latched in the A state and but we desire to reset it to the B state. We proceed as follows: If any of the causative factors S1, S2, or S3 is still being applied S lowthen in this case there is a clear cause, explaining the state of the latch.
Since we wish to reset the latch, the first order of business is to remove whatever causes are setting it. That is a sufficient cause that will reset the latch.
Statistical Language - Correlation and Causation
Either way, the cause is unknowable, lost to history. If the only goal was to set or reset the latch, the history is irrelevant.
We can dictate the new state without knowing what caused the old state. On the other hand, for other purposes — such as policy and planning — it matters a great deal what caused the latch to be set.

This is a problem, because the true cause simply cannot be determined by looking at the current state. Sometimes it may be possible to solve the problem by resetting the latch, and then watching it over time, watching closely so that when the latch gets set you know which input caused it.
In particular, it is entirely possible to have an undesirable positive feedback loop that you can get into but cannot get out of. Also, very often it is utterly impossible to ascertain what caused the current state just by looking at the current state. Galileo made a point of this in The present does not seem to me to be an opportune time to enter into the investigation of the cause of the acceleration of natural motion, concerning which various philosophers have produced various opinions Such fantasies, and others like them, would have to be examined and resolved, with little gain.
For the present, it suffices The laws of physics must say what happens, but they need not say how it happens, and they almost never say why it happens. This is tremendously important. What was lacking in physics, from the time that Aristotle coined that word to name the science of nature, was the idea that actual measurement could contribute anything of real value to any science.
The object of science, as set by Aristotle, was to find out the hidden causes of events in nature. Measurement could not reveal underlying causes of the kind required by philosophers, so measurement had no place in physics.
Let me say it again: This is what sets modern science apart from medieval science. This is what sets physics apart from metaphysics and philosophy. Newton went to school on Galileo literally and figuratively.
Seventy five years later, Newton expressed the same idea, explicitly disclaiming causation: Hactenus Phaenomena caelorum et maris nostri per Vim gravitatis exposui, sed causam Gravitatis nondum assignavi Hitherto we have explained the phenomena of the heavens and of our sea by the force of gravity, but have not yet assigned the cause of this force Anything that blurs the distinction between causation and force sets science back almost years. Sometimes we know F and x, and infer k.
Sometimes we know x and k, and infer F. Sometimes we know k and F, and infer x.
Sometimes we know F, and infer kx without knowing k or x separately. Item 4 applies to a number of common situations, such a force of constraint.
For example, consider a block resting on the table, in equilibrium. We know that the tabletop must be slightly springy, just because all materials are.
This allows us to understand the process whereby the block came to be in equilibrium. We believe that the tabletop has a spring constant k that is very large, but not infinite. We assume that in equilibrium, the block deforms the tabletop by a small amount x, such that the product kx provides just enough force to counterbalance the weight of the block.
The primary requirement is that the product kx must have the right value. The physics here may be easier to visualize if you place a block on a not-very-taut rubbery drumhead rather than a tabletopso that the deformation is large enough to be seen. A force is a force. It does what it does. With remarkably few exceptions, the laws of physics are invariant under a reversal of the time variable.
Thermodynamics has an arrow of time. Some of the laws of thermodynamics are inequalities, not equalities. Kaon decay is not invariant under time-reversal. A special food may be tested on poultry.
But there may be a regression relationship between two variables and in which there is no cause and effect casual relationship between them. In some cases a change in does cause a change inbut it does not happen always.
Sometimes the change in is not caused by change in. The dependence of should not be interpreted as a cause and effect relationship between and In regression analysis, the word dependence means that there is a distribution of values for given single value of.
Cause and Effect
For a given height of 60 inches for men, there may be very large number of people with different weights. The distribution of these weights depends upon the fixed value of.
It is in this sense that the word dependence is used. Thus dependence does not mean response effect due to some cause. Some examples are discussed here to elaborate upon the idea.Explicit Cause and Effect Relationships
