Suppose the grades are an A for a 3 credit class, two B's for the 4 credit classes and a C for a 2 credit class. Note that the average calculator will compute the average for all values that are weighted equally. For a weighted average, such as GPA and other statistical applications, the weighted average calculator linked above is the tool you want to use.
In statistics the mean is known as a measure of central tendency. The four averages are the mean, median, mode and range. The mean is what you typically think as the average - found by sum all values and dividing the sum by the number of values. The median is the middle value of the set or the average of the two middle values if the set is even.
To calculate all these averages and more, check out the Mean Median Mode Calculator. We calculate averages because they are a very useful way to present a large amount of data. Instead of having to trawl through hundreds or thousands of pieces of data, we have one number that succinctly summarises the whole set. While there are some problems with averages, such as outliers showing an inaccurate average, they are useful to compare data at a glance.
Averages can be misleading for a number of reasons. They best represent evenly distributed bell curves , where most results are found in the middle, and few on the extremities. But even one very extreme point can change the average dramatically , and so these anomalies are often excluded, but not always. Next, humans tend to interpret averages as being perfect representations , leading to a lack of desire to understand the nuances of the data.
Lastly, averages are often used to predict individual cases, which are often wildly inaccurate. There is no easy answer to whether the average is better than the mode - it depends entirely on the data set in front of you. If the data is normally distributed, has no outliers, then you should probably use the average , as it will present you with the most representative value.
The mode, however, is more robust , and will present the most common value, regardless of any outliers. The mode should always be used with categorical data - that is, data with distinct groups - as the groups are not continuous. Although it is easier to use the Omni Average Calculator, to you calculate average percentage in Excel:. You can average averages, but it is often very inaccurate and should be done carefully.
Whether you should use the average or the median will depend on the data you are analysing. If the data is normally distributed, has no outliers, then you should probably use the average , although the value will be quite similar to that for the median.
If the data is heavily skewed, the median should be used as it is less effected by outliers. The average of averages is not accurate - most of the time. Data can be misleading due to two main factors, lurking variables and weighted averages. The accepted range is , so an average of The most misleading is the mean because the 4 is an outlier. Log in.
