- Average absolute deviation - The average absolute dispersion or variability. In this general form, the central point can be the mean, median, mode, or the result of another measure of central tendency. Furthermore, as described in the article about averages, the deviation averaging operation may refer to the mean or the median.
- Law of averages - The law of averages is the law that a particular outcome or event is inevitable or certain simply because it is statistically possible. Depending on context or application it can be considered a valid common-sense observation or a misunderstanding of probability.
- Expected value - In probability theory, the expected value of a random variable, intuitively, is the long-run average value of repetitions of the experiment it represents.
- Central limit theorem - In probability theory, the central limit theorem establishes that, for the most commonly studied scenarios, when independent random variables are added, their sum tends toward a normal distribution even if the original variables themselves are not normally distributed.

No ND filter? Or a lens that can't take one? Try taking lots of shots and averaging them instead.

Hi in the session we are going to learn about weighted averages for this let us take an example which you must be familiar with let say there are 3 subjects maths science and languages let’s say you scored 60% in maths 70% in Science and 80% in languages the question is what’s the average percentage marks you scored in these 3 subjects will it be 60 + 70 + 80 divided by 3 the simple average which is nothing but 70% what do you think well that will be true only if all the subjects are out of hundred marks or they are out of equal marks am I right or wrong what if I change the weightages of each subject for example let’s say maths is out of 200 marks science out of 300 and languages out of 500 will the answer still be 70% not really because now I will calculate the individual marks in each subjects for example in maths you would have scored 60% of 200 which is 120 in science you would have scored 70% of 300 which is 210 and in languages you whould have scored 80% of 500 which is 400 the sum total of the marks is 120 + 210 + 400 divide by the over all marks which is 200 + 300 + 500 this is how you will calculate the percentage right and it turns out to be 73% now the question is why isn’t it 70% reason is pretty simple in the earlier case We had assumed that all subjects were equally important because all subject had equal marks with this stand you realise that languages the scores that you scored in this subject must be given more importance because it is out of 500 marks as compared to maths which is only out of 200 marks and hence what we have here is a concept of weighted average so we’ll have to assign some ways to each of these scores for example since their marks are in ratio 2:3:5 will assign the weightages of 2, 3 and 5 respectively to the respective percentages which is 60, 70, 80 which means the average percentage marks will be calculated as 2*60 + 3*70 + 5*80 upon the sum of the weights which is 2 + 3 + 5 and that turns out to be 73% now this concept is what we call the weighted average where in different values are assign different weights depending on their importance let us understand this even better using this example if 3kgs of tea powder costing 10 rupees per kg is mixed with 2kg of tea powder costing 25 rupees per kg what will be the average price of the resulting mixture right now we have two varieties of tea powder

Algarrobo Norte beach in the central coast of Chile. A really beautiful and quiet beach for making photographies. In this case a long exposure of 15 seconds resulting in an averaging of the waves patterns.
