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.
So as one variable goes up the other variable goes up. They are related to each other somehow, and they vary in the same direction. We say that they vary in a direct way or a positive way. In this case the correlation coefficient, r, should come out to be a relatively high positive number.
