Therangeof a data set is a critical concept in statistics, representing the difference between themaximumandminimumvalues. It quantifies variability, indicating how spread out the values are. A larger range signifies more dispersion, whereas a smaller range shows values are closer together. Calculati...

Median: The median is the middle value of the entire data set. It is sometimes referred to as the 2nd quartile or Q2. Interquartile Range (IQR): The interquartile range, or IQR, measures how spread out the middle part of a data set is. It is the difference between the 1st and 3rd...
Line Plots: A line plot is the plotting of a data set in which a number line is taken and the frequencies are plotted as dots above the given observation. For example, if the number 20 has a frequency of 5 then 5dots are put over the number 20. Similarly, ...
The IQR is the middle 50% of the dataset. It’s the range of values between the third quartile and the first quartile (Q3 – Q1). We can take the IQR, Q1, and Q3 values to calculate the following outlier fences for our dataset: lower outer, lower inner, upper inner, and upper out...
For continuous variables, differences were assessed using Student’s t-test or the Mann-Whitney U test (non-normally distributed variables), with results presented as means with standard deviations (SD) and medians with interquartile ranges (IQR). Multivariable logistic regression models were ...
Other measures of dispersion, such as theinterquartile range (IQR)orstandard deviation, can provide a clearer understanding of the data’svariability. Additionally, a range can be misleading if the dataset does not follow anormal distribution. A normal distribution is symmetrical, with equalmean, ...
The interquartile range (IQR) contains the second and third quartiles, or the middle half of your data set.Whereas the range gives you the spread of the whole data set, the interquartile range gives you the range of the middle half of a data set....
all values were scaled by subtracting the median and dividing by the interquartile range such that the median of the overall and ROI-level scaled errors was 0.0 (IQR = 1.0) (Supplementary Materials). The final scaled errors, which we named Outlier Index Score (OIS), represent the number...
