But, if you stored the correlation output in a MATRIX. What if you were doing some correlation problems and had several variables? You could use the MTB> corr c1-c3 command and you would get some decimals in your output. However, you can get a little more decimals in DESC if you want. Sometimes however, if you get too greedy, it will list it in scientific notation. The DESC output would have 3 decimals places. So, if you had some data in c1-c3, and then did: there is a subcommand called DECIMAL that will allow you to have some control over the DESCRIBE output. If you have some data in columns and want to DESCRIBE the data. Are you stuck therefore? Is there nothing you can do?Įssentially YES but, here are a couple of suggestions. and what you normally get depends on the variables you have, and some compromise for decimal places. Minitab uses some internal algorithm for 'deciding' on this. Well, the bottom line is that you do NOT have much control over decimal placement. even if you had taken it 10 more places out and had rounded BACK to 3. even though you don't see them in output. How can I get Minitab to give me more control over decimal placement?įirst, it is important to understand that the actual calculations for work done in Minitab carry many, many places. the ranks would then be 1, 2, 3, and 4 respectively. If you did that with the data 34, 23, 19, and 10. If you use a LET command like the following, you can get Minitab to REVERSE the way it ranks values. How can I get Minitab to 'cooperate'? Well, again, say that the data that you want to rank are in c1. and the big rank values would be assigned to the LOW data values ie, just the OPPOSITE to what Minitab does. But, in many cases, high data values mean good or the best and, those are the values you want to assign the ranks of 1 or 2 or 2 to. and the data are in c1, then using the MTB> rank c1, c2 command will put the rank values of 4, 3, 2 and 1 in c2. So, if the numbers are 34, 23, 19, and 10. When the data points are lined up in order, from high value to low value, then Minitab will assign the LOWEST rank value (=1) to the LOWEST data value, and the HIGHEST rank value to the HIGHEST data value. There is a command in Minitab called RANK. Thus, somethimes big numbers should have high ranks and other times, low ranks.

However, in other cases, like professional averages for strokes per rounds over the year, a rank of 1 would be assigned to the golfer with the LOWEST score. Lose data with single column commands How do I get Mintab to rank data correctly?Ever need to rank some data? Well, in some cases, like Grade Point Averages, we would assign a rank of 1 to the highest or largest GPA value.Dennis RobertsĬlick on the link to the FAQ you want an answer to If you have some suggestions for questions that I can post answers to here.
