### 3. Creating a Histogram in Excel

Statisticians often use histograms as visual representations of numerical data, that indicate the number of data points that fall within specified ranges. Â So we have put together a list of tutorials that go over what histograms are and how to create them in Excel:

**The Definition of a Histogram:**We usually use a Column chart to represent numerical data in Excel. A Histogram does a specific task of the Column chart showing the number of occurrences of a variable graphically in a specified range, called a bin. In short, a histogram visually shows the count of elements that fall within sequential, non-overlapping intervals. The Histogram also identifies trends in data and detects unusual patterns like Outliers. That is why the Histogram is quite popular as a useful data analysis tool in business.**How to Create a Histogram in Excel:**Follow this article from our website to create a histogram. The**Data Analysis**Toolpak is covered as well as how to create a histogram with bell curve.**The Differences between a Bar Graph and a Histogram:**In the differences between a bar graph and a histogram tutorial, we review this commonly asked question, as well as how to create each in Excel. We also look at the types of data sets that the bar chart and the histogram are used to visually showcase.

### 4. Correlation in Excel

Correlation evaluates the linear relationship between two variables and gives one an indication of the strength of the relationship between the two variables of interest. We have selected one tutorial that covers how to calculate the correlation between two variables in Excel:

In addition, common errors associated with correlation are reviewed. The article also comes with an accompanying video tutorial.

### 5. Regression in Excel

Regression analysis is a commonly utilized predictive technique that analyses how well predictor variables or independent variables do in predicting the outcome or dependent variable. So we have put together a list of tutorials to explain to you what regression is all about as well as how to calculate it in Excel:

**Regression: **In statistical modeling, the regression analysis estimates the relationship between multiple variables, for instance: dependent and independent variables. It explains how the dependent variable changes as independent variables change to identify mathematically which variable affects the outcome. After identifying, it predicts which factors to consider or ignore and forecasts the output.**
**Here are different regression analyses of Statistics:

**Simple Linear Regression:**Simple linear regression looks at how a dependent variable is related to one independent variable using a straight line.**Multiple Linear Regression:**We use multiple linear regression to predict the dependent variable using two or more independent variables.**Quantile Regression:**Quantile regression is a way of analyzing data that estimates the middle value (median) of the response variable instead of the mean, which is what regular regression does. Itâ€™s used when regular linear regression doesnâ€™t work well.**Non-Parametric Regression:**Nonparametric regression is a type of regression where the predictor isnâ€™t assumed to have a specific shape in advance; itâ€™s determined based on the data itself. This method needs larger sample sizes compared to parametric regression. So, it relies on the data to establish the modelâ€™s structure and estimates without predefined assumptions.**Polynomial Regression:**In statistics, polynomial regression models the relationship between x and y by using a polynomial equation of a specified degree.

**Using the Regression Data Analysis Tool in Excel: **In this tutorial from our website, how to calculate linear regression using the **Data Analysis Toolpak** in Excel is explained.

**Multiple Regression Analysis: **Multiple regression is used when you want to investigate the relationship between a dependent variable and two or more independent variables. In our multiple regression analysis with Excel tutorial, we cover how to do multiple regression using a worked example.
