Histogram

Meaning in statistics, with examples

/ˈhɪstəɡræm/nounCore term

In statistics, histogram means: A chart of touching bars showing how many observations of a numeric variable fall into each interval, called a bin.

In Turkish: histogram, sıklık grafiği

How it is used

Used to check the shape of a distribution: symmetry, skewness, peaks and gaps. The chosen bin width can change the picture a lot. Unlike a bar chart, the x-axis is a numeric scale, so there are no gaps between the bars.

Example sentences

  1. The histogram of delivery times has a long tail to the right.

  2. Try a narrower bin width; this histogram hides too much detail.

Common collocations

  • plot a histogram
  • bin width
  • histogram of residuals
  • frequency histogram
  • bar chartA chart that compares categories using separate rectangular bars whose lengths show counts, percentages or other values.
  • distributionThe pattern showing which values a variable takes and how often each one occurs, often pictured as a histogram or a curve.
  • skewedDescribes a distribution that is not symmetric and has a longer tail on one side; in a right-skewed distribution a few very large values stretch the tail to the right.
  • frequencyThe number of times a value or category occurs in a data set; a relative frequency gives the same information as a proportion or percentage.
  • box plotA chart that shows the median, the quartiles and the spread of the data as a box with lines (whiskers) extending from it, with outliers marked as separate points.
