Is it okay to compare box plots with different number of data (number of n)? Thank you very much.
A box plot, also known as a box and whisker plot, is a graphical representation of a set of data that shows the distribution of the data. It includes the minimum and maximum values, the first and third quartiles, and the median. The box in the plot represents the middle 50% of the data and the "whiskers" on either side represent the upper and lower values of the data.
A box plot can be interpreted by looking at the different components of the plot. The median, which is the middle value in the data set, is represented by the line in the middle of the box. The length of the box shows the range of the middle 50% of the data. The whiskers show the variability of the data, with values outside of the whiskers being considered outliers.
To compare box plots with different numbers of data points, you can look at the overall shape of the plots. If the shapes are similar, it could indicate that the data sets have similar distributions. You can also compare the medians and ranges of the data sets to get a better understanding of the differences between them.
If the boxes in two box plots have different lengths, it means that the middle 50% of the data in each data set have different ranges. This could indicate that the data sets have different distributions or that one data set has more variability than the other.
Box plots can be used to compare groups or categories by creating multiple box plots side by side. This allows for a visual comparison of the medians, ranges, and shapes of the data sets. Additionally, you can also use statistical tests, such as the t-test or ANOVA, to determine if there are significant differences between the groups.
