Edward Montes, the managing director for North America at Havas Digital, who oversees its exchange group, says that his data analysts are "basically looking for anything that affects performance — any time they find variance in the matter of how the media performs, that's what they go in and exploit, and that's what the exchanges are perfectly set up to do".

British Journal of Cancer

However, they ruled out a Poissonian distribution of protein copy number, because they found variance to be equal to roughly 1000 times the mean of expression, over a wide range of conditions.

Bioinformatics

Ordas et al. (2008) found variance-controlling QTL in maize where the allele effects resulted in an increase of the residual variance of 30 40%.

Expert writing Tips

Best practice

When writing about statistical analysis, use "find variance" to clearly indicate the process of calculating or determining the spread of data points around the mean. Ensure the context provides enough information about the data being analyzed.

Common error

Avoid implying that simply "finding variance" establishes a cause-and-effect relationship. While variance can highlight differences or discrepancies, further analysis is typically needed to determine the underlying causes.

Linguistic Context

The phrase "find variance" functions primarily as a verbal phrase indicating the action of determining or calculating the variance in a dataset or situation. As Ludwig AI indicates, it’s usable in contexts related to statistics, data analysis, or research.

Ludwig's WRAP-UP

In summary, the phrase "find variance" is a grammatically sound and technically specific term predominantly used in scientific and academic contexts. Ludwig AI confirms its correct usage for describing the process of determining the dispersion within data. While semantically interchangeable alternatives like "calculate variance" or "determine variance" exist, it's crucial to avoid implying causation solely based on variance. Its usage is relatively rare but appropriate in statistical analysis and research discussions. Understanding its function and avoiding common errors ensures clear and accurate communication in technical writing.

FAQs

What does "find variance" mean in statistical terms?

In statistics, "find variance" refers to the process of calculating a measure that quantifies the spread or dispersion of a set of data points around their mean value. It involves determining how much individual data points deviate from the average.

How do I use "find variance" in a sentence?

You can use "find variance" in a sentence like this: "To understand the data's distribution, we need to "calculate variance" and standard deviation."

What are some alternatives to saying "find variance"?

Alternatives to "find variance" include "determine variance", "measure variance", or "assess variance". The choice depends on the specific context and the emphasis you want to convey.

What's the difference between "find variance" and "analyze variance"?

"Find variance" refers to the process of calculating the statistical measure of variance. "Analyze variance", on the other hand, suggests a broader investigation into the factors contributing to the observed variance, often involving techniques like ANOVA (Analysis of Variance).
