Study Notes
Histogram Overview
- A histogram is a graphical representation of continuous frequency data using vertical bars.
- Histograms help visualize the distribution of data points across intervals.
Types of Histograms
-
Uniform Histogram
- Characterized by bars of equal height, indicating a consistent frequency across intervals.
-
Symmetric Histogram
- Divisible into two nearly mirror-image halves by a vertical line; suggests equal distribution of data.
- If the highest point (mode) is at the center and decreases symmetrically on either side, it represents a Normal Distribution, also known as a Bell Curve.
-
Unimodal Histogram
- Contains a single peak, indicating that most data points cluster around one value or area.
-
Bimodal Histogram
- Displays two distinct peaks, resembling a two-humped camel, revealing the presence of two prevalent values or groups in the data.
Skewness in Histograms
-
Left Skewed Histogram
- Data points are concentrated on the right side, resulting in a longer tail on the left. This indicates that the mean is less than the median.
-
Right Skewed Histogram
- Data points are more densely packed on the left side, leading to a longer tail on the right. In this case, the mean is greater than the median.
