What is meant by "Range Life"? Chartstopper wrote: The title "Range Life" appears to be Malkmus's translation of the French term "une vie rang�e," which means an ordered, structured life. A range life would be an ordinary life, an "arranged" life, a comfortable life, a life of shady lanes perhaps. Malkmus probably studied French at UVA.

To find the range in statistics, take the largest value and subtract the smallest value from it. Range = Highest value – Lowest value It cannot be a negative value because the formula takes the larger value and subtracts the smaller value. Related post: Measures of Variability
For example, in the worksheet below, Dataset 1 has a range of 38 – 20 = 18, while for Dataset 2 it is 52 – 11 = 41. Dataset 2 has a broader range and, therefore, is more variable than Dataset 1. Conveniently, you can find the minimum, maximum, and range values in the descriptive statisticsoutput from statistical software. Excel’s Descriptive Statis...
You can find data ranges in several types of graphs, including histograms, boxplots, and scatterplots. In the example graphs below, the red lines represent the ranges. The following graphical representations bring the concept to life. If you’re looking at a chart and don’t have the data, you’ll have to approximate the values visually.
The range is simple to understand but it has some limitations you need to consider. Unfortunately, outliers can influence it considerably because it uses only the two most extreme values. If one value in the dataset is atypically low or high, it changes the entire range all by itself. Let’s return to the first two data sets in this post. However, I...
Taking the weaknesses into consideration, when is the range a good measure of variability? It can be an excellent measure when you need an intuitive statistic that indicates the degree to which the data are spread out. Everyone can understand the concept of the difference between the maximum and minimum data points. It’s also easy to calculate in y...
Quality control analysts often use this particular measure of variability. For starters, if the range for a batch of products is larger than the spread of the upper and lower spec limits, they know that at least one part is out of spec! For example, if the range of part lengths is 5mm, but the spread for the spec limits is 3mm, there must be parts ...
- Why Understanding Variability is Important. Let’s take a step back and first get a handle on why understanding variability is so essential. Analysts frequently use the mean to summarize the center of a population or a process.
- Range. Let’s start with the range because it is the most straightforward measure of variability to calculate and the simplest to understand. The range of a dataset is the difference between the largest and smallest values in that dataset.
- The Interquartile Range (IQR) . . . and other Percentiles. The interquartile range is the middle half of the data. To visualize it, think about the median value that splits the dataset in half.
- Variance. Variance is the average squared difference of the values from the mean. Unlike the previous measures of variability, the variance includes all values in the calculation by comparing each value to the mean.
Range vs. Standard Deviation: Similarities & Differences. The range and standard deviation share the following similarity: Both metrics measure the spread of values in a dataset. However, the range and standard deviation have the following difference: The range tells us the difference between the largest and smallest value in the entire dataset.
The range of hybrid vehicles, meanwhile, depends on both fuel and battery life. Many hybrid vehicles rely on their internal combustion engine for power while the battery pack serves as a backup. There are also some hybrids with batteries that send power to the wheels while the combustion engine recharges them while driving.
