Metric-dimension combinations are an important tool for measuring data performance. They are used to analyze and interpret information from a variety of sources, such as web analytics, marketing campaigns, and customer surveys. In order to get the most accurate results, it is essential to understand which combinations are valid and which are not. This article will discuss what metric-dimension combinations are not valid and why.

## Understanding Metric-Dimension Combinations

Metric-dimension combinations are the combination of a particular metric and a particular dimension that are used to measure and interpret data. Metrics are measurable values that are used to quantify performance, such as page views, time on page, or bounce rate. Dimensions are the characteristics of the data that are used to categorize or group the metrics, such as page type, device type, or user location.

When used together, metrics and dimensions can be used to gain insight into the performance of a website, marketing campaign, or customer survey. For example, a website might use the metric of page views combined with the dimension of user location to track how many people from different locations are viewing the website.

## Examining Invalid Combinations

Not all metric-dimension combinations are valid. In order for a combination to be valid, the metric and dimension must be related. For example, a website might track the metric of page views combined with the dimension of user location. However, page views cannot be combined with the dimension of page type, as page views are not related to page type.

Additionally, some metrics are not compatible with certain dimensions. For example, time on page is a metric that measures the amount of time that a user spends on a page. It cannot be combined with the dimension of user location, as user location does not affect the amount of time spent on a page.

Finally, some metrics are not compatible with certain data sources. For example, page views can be tracked using web analytics data, but cannot be tracked using customer survey data, as customer surveys do not provide information about page views.

In conclusion, it is important to understand which metric-dimension combinations are valid and which are not. Metrics and dimensions must be related, and some metrics are not compatible with certain dimensions or data sources. Understanding which combinations are not valid can help to ensure that the data is accurately interpreted and that the most accurate results are obtained.
