I have a set of data with a mean of 55.05 and a standard deviation of 7.51. However, I want to transform these data to a list of values with a mean of 55.62, a standard deviation of 58.69, and the list should not contain negative values. Is this possible? Thank you The list of data is below: 63,25343492 58,46647552 70,1893707 62,02920512 46,81912721 38,62651421 54,91834215 53,5648866 66,58933926 53,44316012 66,35574684 61,4587485 39,3649 45,85913993 48,00987736 70,02203183 55,09231297 53,05058226 61,80686162 70,89394706 48,53529541 64,26565334 47,80300402 59,23700534 51,88877063 38,69512242 64,4900316 49,49378877 60,15633028 55,56446765 63,18853348 59,33611195 70,10515712 48,17858153 57,68142533 51,03872336 69,40552751 53,59097579 52,80740962 52,30157743 56,08804551 53,03329499 52,04072179 53,5688407 63,04249864 52,93057395 43,13632994 52,36371528 55,35402605 57,1120537 60,48213353 48,71669955 58,83728766 53,12609614 53,03303446 47,03379664 50,20478272 52,80171426 51,55706095 56,0172937 46,56791444 38,96889239 53,14244022 60,06590358 65,1300528 73,4724206 57,4408382 55,85660987 52,4207217 61,09611171 53,45293161 55,1140787 55,88977952 52,99888866 63,57548193 59,21058636 52,28955351 70,71567257 51,58985465 64,5838287 49,87066563 47,25890702 47,0767081 54,10798435 55,77987579 52,29006138 63,52081038 59,82786897 43,32256542 53,84019996 49,43879073 65,83450715 55,11900566 48,51611519 69,89401638 50,46511071 60,63654817 52,64315423 57,37887843 27,69265302 49,14289887 58,8887636 70,6123843 66,95574219 56,98665343 69,66994482 60,10217979 55,68536966 49,31678724 52,80025991 42,7260427 46,77761073 54,01579331 49,40364238 48,09137352 41,42521403 56,78384303 42,94948767 49,61580545 54,78690354 40,84314573 55,89356544 58,5912459 58,81514928 39,70456407 58,04789421 60,29536381 52,16125774 55,26669272 63,04562829 55,28027981 57,46656792 53,70214918 58,79549087 59,46990521 55,31339009 58,37461096 64,63075033 47,02739224 56,73003551 42,36365324 50,83343298 55,69348894 69,6040837 62,24566527 53,64166025 51,24845592 42,27381025 64,40506612 63,25815082 56,24299769 68,70028498 52,93784239 54,43262017 52,98691751 49,02647202 50,66430009 37,10591106 58,28431947 44,79790575 54,94091585 64,1397584 64,62166149 62,7770689 55,50020929 60,43260991 47,68335848 60,85639191 63,27062325 56,9093851 60,4381041 53,08066183 42,87721556 46,75362556 56,52171112 57,12483612 47,79726248 54,09436429 61,1144147 56,753991 46,52390151 54,0095505 57,58468327 46,85270249 69,23396741 65,02744389 53,75206855 54,63300996 60,5300577 43,98179652 51,65379312 43,36955301 62,92077546 50,92264608 58,52230791 53,47326278 54,482589 43,88931527 53,98827615 53,55388171 59,34192933 51,1088057 50,20534665 36,42917504 61,57306474 53,4040016 44,6422808 65,68931656 56,36393928 46,19969771 54,67038106 58,72142474 55,37179809 52,14944159 53,73874199 60,47480244 56,52727128 40,94344286 63,44741701 63,49801903 58,94707596 52,26117562 43,90568903 59,71872045 60,50918239 62,48497944 58,69732414 59,16129688 53,42235077 62,30943885 54,61844341 61,54267517 59,26788629 50,10868374 64,08723045 52,65740089 66,01882658 49,48888488 50,78264958 64,4557242 54,47369803 50,40597059 42,45460429 53,63955293 49,3218758 49,61972988 57,22906427 55,60043386 55,07462007 55,92224343

You can always make up a list of numbers to give you any mean and standard deviation you want. You need to be more specific as to what you want to do.

You could put some extreme value into the set to acheive a change. Perhaps add the value 975 and replace the first ten values with 1s.

Maybe you need to be a bit more specific on why you want to do this...
