The GAUSS function in Google Sheets is a powerful statistical tool used to determine the likelihood of a random variable falling within specified deviations from the mean in a normal distribution. This function is particularly useful in fields like finance, research, and any area that involves statistical analysis, allowing users to evaluate probabilities effectively.

Syntax

GAUSS(z)  

• z: This parameter represents the number of standard deviations from the mean. It indicates how far away a value is from the average in terms of standard deviations.

Example #1

GAUSS(1)

This function calculates the probability that a random variable is within one standard deviation of the mean in a normal distribution. The result will be approximately 0.3413, indicating that about 34.13% of values lie within this range.

Example #2

GAUSS(-2)

This function evaluates the likelihood that a random variable falls within two standard deviations below the mean. The result will be about 0.4772, meaning approximately 47.72% of values are found within this segment of the distribution.

Example #3

GAUSS(3)

This function gives the probability of a random variable being within three standard deviations above the mean. The result will be near 0.4987, which signifies that nearly 49.87% of values are contained within this upper range.

Error handling

• NUM!: This error occurs if the z value provided is non-numeric or outside the acceptable range.
• VALUE!: This may show up if the argument is not valid or is missing. Ensure that a valid numeric value is entered.

Conclusion

In summary, the GAUSS function is essential for anyone working with probability and statistics within Google Sheets. It allows users to quantify the likelihood of occurrences within a normal distribution, making statistical analysis more accessible and efficient. Understanding and applying this function can enhance data interpretation skills and aid in informed decision-making.
