Frequency Distribution Curve
A frequency distribution curve, also known as a frequency curve, is a graphical representation of a data set’s frequency distribution. It is used to visualize the distribution and frequency of values or observations within a dataset. Let’s understand it’s different types based on the shape of it, as follows:
Frequency Distribution Curve Types | |
---|---|
Type of Distribution | Description |
Normal Distribution | Symmetric and bell-shaped; data concentrated around the mean. |
Skewed Distribution | Not symmetric; can be positively skewed (right-tailed) or negatively skewed (left-tailed). |
Bimodal Distribution | Two distinct peaks or modes in the frequency distribution, suggesting data from different populations. |
Multimodal Distribution | More than two distinct peaks or modes in the frequency distribution. |
Uniform Distribution | All values or intervals have roughly the same frequency, resulting in a flat, constant distribution. |
Exponential Distribution | Rapid drop-off in frequency as values increase, resembling an exponential function. |
Log-Normal Distribution | Logarithm of the data follows a normal distribution, often used for multiplicative data, positively skewed. |

Frequency Distribution – Table, Graphs, Formula
Frequency Distribution is a tool in statistics that helps us organize the data and also helps us reach meaningful conclusions. It tells us how often any specific values occur in the dataset.
A frequency distribution represents the pattern of how frequently each value of a variable appears in a dataset. It shows the number of occurrences for each possible value within the dataset.
Let’s learn about Frequency Distribution including its definition, graphs, solved examples, and frequency distribution table in detail.
