What is the mathematical symbol for average?

The mathematical symbol for average is sometimes denoted by putting a line above the variable, like this: _ X The "Expectation value" of a random variable - is like a weighted average. E[X] or <X> or the Greek letter mu (µ) - are a few of the common symbols for the Expected Value of X. A random variable may, for example, represent your high school grades for each course taken, where each course has a different weight. The expectation value would be your weighted average of high school grades.


In what condition average velocity is equal to average speed give an example?

When an object is moving along a straight line at a variable speed, we can express the magnitude of the rate of motion in terms of average velocity.It is the same way as we calculate average speed.


The average time it takes a swimmer to complete a lap is represented by the variable t which set of numbers best describes the value of the variable?

the best set of numbers is irass-anal numbers. so if you want to find it it is irass-anal numbers stupid fuck's


How do box plots describe data?

Box [and whisker] plots show 5 key statistics of a set of numerical data. It is of no use for qualitative data. From the smallest to the largest, the statistics plotted are:The minimum valueThe lower quartile (the value of the variable that is greater than a quarter of the observations)The median (the value of the variable that is greater than half the observations)The upper quartile (the value of the variable that is greater than three quarters of the observations)The maximum value.(In slightly refined versions, outliers are separately identified).The median is a measure of central tendency (average value). The difference between the quartiles is a measure of dispersion or spread around the average. The relative values of the five indicate whether or not the data set is skewed.Box [and whisker] plots show 5 key statistics of a set of numerical data. It is of no use for qualitative data.

How do you find the average on a frequency table?

* To find the mean (or average) of a standard frequency table, you must firstly cross-multiply the frequncies with the independent variable in the left column. * Then, add up these products and divide by the total number of frequencies. * For grouped frequency tables, you must find a mid-point, a half-way value in each group, before cross-multiplying.
