How to Find Data Distribution
Data distribution refers to the way in which a set of data is spread out or distributed. There are several types of data distributions.
Step-by-step to find data distribution
To find several types of data distributions, follow the below guide:
- Normal Distribution: Also known as the bell curve, this is a symmetric distribution in which the data is clustered around the mean, with fewer observations in the tails.
- Skewed Distribution: A distribution that is not symmetric, but instead has a tail that stretches out to one side. There are two types of skewed distributions: positively skewed and negatively skewed.
- Bimodal Distribution: A distribution in which there are two distinct peaks in the data, indicating that there are two different groups of observations.
- Uniform Distribution: A distribution in which the data is spread evenly across the entire range of values.
- Outliers: A data point that is significantly different from the other observations in the dataset.
It’s important to be aware of the type of data distribution when analyzing data, as the distribution can affect the interpretation of the data. For example, if a dataset has a normal distribution, the mean, median, and mode will be the same. However, if the dataset has a skewed distribution, the mean and median will be different.
There are various tools such as histograms, box plots and quantile-quantile plots that can be used to visualize the distribution of a dataset.
