How to get Statistical Summary of a Dataset

A statistical summary is a set of descriptive statistics that provide an overview of the key features of a dataset. In this essay, we will go over the steps needed to get a statistical summary of a dataset in Python.

The first step is to load the data that you want to analyze. This can be done using a library such as Pandas or Numpy. Once the data is loaded, you can use the “describe()” function in Pandas to get a statistical summary of the data. This function returns the count, mean, standard deviation, minimum, 25th percentile, median, 75th percentile, and maximum of the data.

For example, if you have a dataset loaded into a Pandas DataFrame called “data”, you can use the “data.describe()” command to get a statistical summary of the data. This command will return a table with the statistics for each column of the data.

Similarly, if you have a dataset loaded into a Numpy array called “data”, you can use the “np.mean()”, “np.std()”, “np.min()”, “np.percentile()”, “np.median()”, “np.max()” functions to get the statistical summary of the data.

It’s important to note that the statistical summary of the data can provide a lot of insights about the dataset, it can help you to understand the distribution of the data, the presence of outliers, and the skewness of the data.

Another important aspect to consider is that some datasets could have missing values, in that case, it’s important to handle the missing values before calculating the statistical summary. There are several techniques to handle missing values, such as dropping the missing values, imputing the missing values, or using the data as it is.

In conclusion, getting the statistical summary of a dataset in Python is a crucial step in understanding the data. The statistical summary of the data can be obtained using the “describe()” function in Pandas, or using functions such as “np.mean()”, “np.std()”, “np.min()”, “np.percentile()”, “np.median()”, “np.max()” in Numpy. The statistical summary of the data can provide a lot of insights about the dataset, it can help you to understand the distribution of the data, the presence of outliers, and the skewness of the data. Moreover, if the dataset has missing values, it’s important to handle them before calculating the statistical summary, there are several techniques to handle missing values, such as dropping the missing values, imputing the missing values, or using the data as it is.
