Q62 Define the following two [2] types of Correlation: [2 Marks] (a) Positive correlation (b) Negative correlation

Answer 1

Positive connection is a connection between two factors wherein the two factors move couple—that is, in a similar course. A positive relationship exists when one variable reductions as the other variable declines, or one variable increments while different increments. A flawlessly positive relationship implies that 100% of the time, the factors being referred to move together by precisely the same rate and heading. A positive connection can be seen between the interest for an item and the item's related cost. In circumstances where the accessible inventory remains the equivalent, the cost will rise if request increments. positive relationship can be one approach to build the hazard in a portfolio (and negative connection is an approach to lessen chance).

It is essential to recall, nonetheless, that relationship doesn't mean causation. As such, in light of the fact that two things are decidedly corresponded doesn't imply that one is causing the other to go a similar way. Also, negative or positive relationship between's two factors doesn't exist under each condition.

Negative connection is a connection between two factors wherein one variable increments as different reductions, and the other way around. In measurements, an ideal negative connection is spoken to by the worth - 1, a 0 shows no relationship, and a +1 demonstrates an ideal positive connection. An ideal negative connection implies the relationship that exists between two factors is negative 100% of the time

An example would be a negative cross-sectional connection among sickness and inoculation, on the off chance that it is seen that where the occurrence of one is higher than normal, the frequency of the different will in general be lower than normal. Likewise, there would be a negative fleeting connection among disease and inoculation on the off chance that it is seen in one area that occasions with a higher-than-normal occurrence of one will in general match with a lower-than-normal rate of the other.
