![]() ![]() The second issue is that sometimes the number of significant digits displayed in the formula on the chart is very limited. However, if you change the data set used to obtain the equation, that equation you manually entered will not update, leaving your spreadsheet with an erroneous equation. If you want to use that equation anywhere in your spreadsheet, you have to manually enter it. The first is that the equation displayed on the chart cannot be used anywhere else. The chart trendline method is a quick way to perform a very simple linear regression and fit a curve to a series of data, but it has two significant downfalls. Linear Regression with the LINEST function Now we know that the data set shown above has a slope of 165.4 and a y-intercept of -79.85. We’d follow these 6 steps (in Excel 2016): Let’s say we have the data set below, and we want to quickly determine the slope and y-intercept of a best-fit line through it. You can go from raw data to having the slope and intercept of a best-fit line in 6 clicks (in Excel 2016). Add the equation to the trendline and you have everything you need. When you need to get a quick and dirty linear equation fit to a set of data, the best way is to simply create an XY-chart (or “Scatter Chart”) and throw in a quick trendline.

In this case A5 is greater than B2, so the result will return FALSE. If A5 is NOT greater than B2, format the cell, otherwise do nothing. If A2 is greater than B2, format the cell, otherwise do nothing. Using the earlier Dates example, here is what the formulas would be. Next, select the “ Use a formula to determine which cells to format” option, enter your formula and apply the format of your choice. When you do this you can omit the IF function and use AND, OR and NOT on their own.įrom the Home tab, click Conditional Formatting > New Rule. You can also use AND, OR and NOT to set Conditional Formatting criteria with the formula option. Using AND, OR and NOT with Conditional Formatting In this case, A5 is greater than B2, so the formula returns FALSE. IF A5 is not greater than B2, then return TRUE, otherwise return FALSE. 03/12/14 is greater than 01/01/14, so the formula returns TRUE. IF A2 is greater than B2, return TRUE, otherwise return FALSE. Here are some examples of using AND, OR and NOT to evaluate dates. You can also substitute Text or Numeric values for the TRUE/FALSE values to be returned in the examples. The remaining True/False arguments are then left as part of the outer IF statement. Note that all of the examples have a closing parenthesis after their respective conditions are entered. IF A7 (“Blue”) is NOT equal to “Red”, then return TRUE, otherwise return FALSE. In this case 25 is not greater than 50, so the formula returns TRUE. IF A6 (25) is NOT greater than 50, then return TRUE, otherwise return FALSE. Here are the formulas spelled out according to their logic: The NOT function only takes one condition. The AND and OR functions can support up to 255 individual conditions, but it’s not good practice to use more than a few because complex, nested formulas can get very difficult to build, test and maintain. NOT – =IF(NOT(Something is True), Value if True, Value if False)įollowing are examples of some common nested IF(AND()), IF(OR()) and IF(NOT()) statements. OR – =IF(OR(Something is True, Something else is True), Value if True, Value if False) When you combine each one of them with an IF statement, they read like this:ĪND – =IF(AND(Something is True, Something else is True), Value if True, Value if False) Here are overviews of how to structure AND, OR and NOT functions individually. The value that you want returned if the result of logical_test is FALSE. The value that you want returned if the result of logical_test is TRUE. IF(NOT()) - IF(NOT(logical1), value_if_true, )) Use the IF function along with AND, OR and NOT to perform multiple evaluations if conditions are True or False. ![]()
