To find the IQR of a ratio on a number line, follow these steps:
Calculate the quartiles (Q1, Q2, and Q3) of the ratios.
Find the IQR by subtracting Q1 from Q3.
The interquartile range (IQR) is a measure of statistical dispersion, equal to the difference between the 75th percentile (Q3) and the 25th percentile (Q1) of a dataset. To find the IQR of a ratio on a number line, follow these steps:
Calculate the quartiles (Q1, Q2, and Q3) of the ratios. This can be done using various methods, such as using a statistical calculator or sorting the ratios and identifying the median (Q2) and the values halfway between the median and the minimum and maximum values (Q1 and Q3).
Find the IQR by subtracting Q1 from Q3. This will give you the difference between the 25th and 75th percentiles of the ratios, representing the middle 50% of the data.
Remember that the IQR is only applicable to data that is at least approximately symmetric. If the data is heavily skewed, the IQR may not be an accurate representation of the spread of the data.
