What is downside probability?
This is a very simple statistic to comprehend and to calculate. It takes the frequency distribution method of calculating probability. The statistic is calculated as This statistic is simple to interpret as well. What it calculates is the probability of the portfolio to get a negative return. It can be comprehended that a higher figure would mean a higher probability of fund to do give negative returns.
A double-bar graph is a graphical method of representing the frequency of specific ordered?
pairs
When the results of experimentation or historical data are used to assign probability values the method used to assign probabilities is referred to as the?
relative frequency method
How do you find the probability of an event?
There are two main methods: the empirical method and the theoretical method. Suppose you want the probability of throwing a 6 on one roll of a die. Empirical method: Throw the die lots and lots of times and count the total number of throws as well as the number of throws that result in a 6. The probability of throwing a six is the number of times you get a 6 divided by the total number of throws. Theoretical method: A die is a cube with six equal faces. Assuming the die is fair, each face has an equal probability of turning up. There are no other outcomes possible (the probability of the die ending up on an edge or a vertex are assumed to be zero). So, there are six outcome, and each equally probable, so that each has a probability of 1/6.
