What happens if you collapse a continuous variable into a binary?
Collapsing a continuous variable into a binary means to convert the variable into one of two categories, i.e. "yes" or "no", "true" or "false" or "1" or "0". This can affect the accuracy of certain types of analytics since by simplifying a continuous variable that could have multiple levels, information and insights may be lost that would have been provided by using the variable's full spectrum. Additionally, if the cut-off point for the binary variable is chosen without considering the context of the data, then results may be biased.
How many bricks do you need for a fire pit?

How do I make a black and white image monochrome?
To make a black and white image monochrome, you would need to adjust the levels, or brightness and contrast, of the image. You can do this using various photo editing software, such as Photoshop or GIMP. In the brightness/contrast dialog box, shift the levels at the middle to different points until the image looks the way you want it to. Alternatively, you can convert the image to greyscale if you're more comfortable with that.
Is there a way to find relation between numbers?
