laatikkokaavioista

Laatikkokaavioista, often translated as box plots or box-and-whisker plots, are a standardized way of displaying the distribution of data based on a five-number summary: minimum, first quartile (Q1), median, third quartile (Q3), and maximum. They are particularly useful for visualizing the spread and central tendency of numerical data and for comparing distributions across different groups.

Alaatikkokaavio consists of a rectangular box and lines called whiskers. The box represents the interquartile range (IQR), which is the range between the first quartile (25th percentile) and the third quartile (75th percentile). The median (50th percentile) is marked by a line inside the box. The whiskers extend from the box to the minimum and maximum values within a certain range, typically 1.5 times the IQR from the quartiles. Data points that fall outside this range are often plotted as individual outliers.

The primary advantage of laatikkokaavioista is their ability to quickly convey information about data variability, skewness, and the presence of outliers. They are less susceptible to extreme values than bar charts or histograms, making them ideal for showing the overall shape of the distribution. They are commonly used in statistics, data analysis, and scientific research to compare datasets and identify patterns.
