How To Calculate Outliers In Excel: A Step-by-Step Guide

Data points that are more than 1.5 times the IQR above the 75th percentile or below the 25th percentile are considered outliers.

How to Effortlessly Adjust Excel for Daylight Saving Time


How to Change to Daylight Saving Time in Excel is a process of adjusting the time in a spreadsheet to account for the seasonal change. Daylight saving time (DST) is the practice of advancing clocks by one hour during the summer months, typically from March to November in the Northern Hemisphere. This is done to make better use of daylight hours, reducing the need for artificial lighting and saving energy.

Changing to DST in Excel is important to ensure that dates and times are displayed correctly. If the time is not adjusted, formulas and calculations that rely on time data may produce inaccurate results. Additionally, it is important to note that not all countries observe DST, so it is crucial to be aware of the specific time zone settings when working with international data.
