Goal seek is a process of finding the correct input value when only the output is known. It is a tool used in "what-if analysis" on computer software programs like Microsoft Excel. Goal seeking is finding the correct input when only the output is known, and it is often done using the goal seek function in Microsoft Excel or what-if analysis via computer programs. Goal seek is used when the output value is fixed, and we have to make a change in any one of the input values. It is a feature of the spreadsheet software that allows users to determine the input value required to achieve a specific output value. Goal seek software only works if there is only one input value. It is a useful tool for solving problems in finance, engineering, and other fields where the relationship between inputs and outputs is complex. In class 10, goal seek is taught as part of the IT curriculum, and students learn how to use it to analyze data in a spreadsheet.
