https://community.jmp.com/t5/Discussions/Mixing-speed-factor-type/m-p/564480#M77691 Hi,<BR />I am going to make a DOE and one of the factors there is mixing speed. The speeds i would like to check are 2,5 and 7 m/s. Should i choose it as categorical factor or continues (but 5 is not exactly the mid point)<BR />Please advise<BR />Thanks Thu, 08 Jun 2023 21:12:49 GMT YanivD 2023-06-08T21:12:49Z https://community.jmp.com/t5/Discussions/Mixing-speed-factor-type/m-p/564480#M77691 Hi,<BR />I am going to make a DOE and one of the factors there is mixing speed.
