For instance, the Google Popular Times histogram mentioned earlier in this post displays a restaurant’s peak hours, where it is the most busy. This information means you know what to expect and can decide if you would still like to visit or come back at a more convenient time, or go at...

In this tutorial you’ll learn how to make a histogram in Google Sheets with a normal distribution curve overlaid, as shown in the above image, using Google Sheets. It’s a really useful visual technique for determining if your data is normally distributed, skewed or just all over the plac...
Skewnessis a measure of the level of asymmetry in the distribution of a dataset. When a dataset is not distributed symmetrically, skewness is observed in the normal curve. Anasymmetric normal curvecan be positively or negatively skewed. Kurtosis Kurtosisis the measure of tailedness in anormal di...
Here’s how I recommend reading a new histogram: Step 1:Look at the overall curve of the graph Is the histogram skewed to the right? Skewed to the left? Or just generally centered? A left-skewed histogram often (but not always!) indicates underexposure, as the shot is full of dark pi...
1. Enter your data into Excel. So, I start by plugging in my data, which I organize into columns and rows. This is basic, but it's all you need to start. Whether you’re importing data from a survey tool, downloading it from yourmarketing platform, or simply typing it in manually,...
Here in the tutorial, we can use the head and tail functions to check different portions of the data set in the output console. The data set summary has also been added as a data frame in the Global Environment, which we can export as a spreadsheet if we wish. ...
In this article, you will not only have a better understanding of how to find outliers, but how and when to deal with them in data processing.
Since this method preserves the variable distribution, it can be affected by skewed distributions and outliers. For example, if there is a single outlier with a very high value, the outlier will receive a value of 1, but the rest of the values will be similar and closer to zero. A...
