Frequency, the crux of a histogram, is the number of data points falling within each bin. The frequency is represented by the height (or, in the case of density histograms, the area) of the corresponding bar in the histogram. The chart's vertical axis typically reflects each bin's raw ...
In a boxplot graph, the box represents the data’s interquartile range (IQR), which is the 50 percent of data points above the first quartile and below the third quartile. Each whisker (line) on the side of a boxplot represents the top and bottom 25 percent of data points, where the...
What is a density curve? A density curve consists of a straight line segment that begins at the origin (0, 0) and has a slope of 1. Sketch this density curve. What are the coordinates of the right endpoint of the segment? (No ...
A Scatter Chart, commonly referred to as a scatter plot, is a graphical representation used to explain the relationship between two continuous variables within a dataset. This visual tool employs a Cartesian coordinate system, where each data point is sy
For example, a population density map uses varying shades to show the difference in population numbers from region to region: CREATE THIS CHART TEMPLATE Create your own map for free with Venngage’s Map Maker. What is data visualization used for? Data, especially a lot of data, can be diffi...
Clustering is an unsupervised learning method that organizes your data in groups with similar characteristics. Explore videos, examples, and documentation.
It is called the “normal probability distribution,” or the normal distribution. It is sometimes called the Gaussian distribution. Normal Probability Density Function The probability density function (PDF) describes the relative likelihood of observing a given value of a continuous random variable. It...
Then the lifting problem is not always solvable. For instance, we have a continuous projection from to , but the identity map cannot be lifted continuously up to , because is contractable and is not. However, if is a discrete space (every set is open), then the axiom of choice lets ...

Medical imaging: Clustering, an unsupervised learning technique, is extremely useful for image segmentation. Clustering algorithms can be applied to medical images and segment them based on pixel density, color, or other features. Doctors can use this information to identify areas of interest, such ...
