After ovulation, the egg lives for about 12-24 hours. Fertilization can take place only during this time period, but the sperm needs at least 9-12 hours inside the woman's body to get ready.That means, your chances getting pregnant are minimal if you make love more than 12 hours after ovulation.ertilization can take place only during this time period, but the sperm needs at least 9-12 hours inside the woman's body to get ready.

When we consider the relationship between two variables, there are three possibilities: 1  Both variables are categorical. 2  Both variables are quantitative. 3  One variable is categorical and the other is quantitative, for instance height and gender.
Correlation is a statistical measure (expressed as a number) that describes the size and direction of a relationship between two or more variables. A correlation between variables, however, does not automatically mean that the change in one variable is the cause of the change in the values of the other variable.Causation indicates that one event is the result of the occurrence of the other event; i.e. there is a causal relationship between the two events.f the correlation coefficient has a positive value (above 0) it indicates a positive relationship between the variables meaning that both variables move in tandem, i.e. as one variable decreases the other also decreases, or when one variable increases the other also increases.
