Mathematics​ ​and​ ​Science Guide​ ​for​ ​Reading ■​ ​What​ ​math​ ​skills​ ​do​ ​scientists​ ​use​ ​in​ ​collecting​ ​data​ ​and​ ​making measurements? ■​ ​What​ ​math​ ​skills​ ​help​ ​scientists​ ​analyze​ ​their​ ​data? Mathematics​ ​is​ ​essential​ ​for​ ​asking​ ​and​ ​answering​ ​questions​ ​about​ ​the​ ​natural​ ​world.​ ​An estimate​ ​is​ ​an​ ​approximation​ ​of​ ​a​ ​number​ ​based​ ​on​ ​reasonable​ ​assumptions.​ ​Scientists​ ​must sometimes​ ​rely​ ​on​ ​estimates​ ​when​ ​they​ ​cannot​ ​obtain​ ​exact​ ​numbers. Accuracy​ ​refers​ ​to​ ​how​ ​close​ ​a​ ​measurement​ ​is​ ​to​ ​the​ ​true​ ​or​ ​accepted​ ​value.​ ​Precision refers​ ​to​ ​how​ ​close​ ​a​ ​group​ ​of​ ​measurements​ ​are​ ​to​ ​each​ ​other.​ ​Both​ ​accuracy​ ​and​ ​precision are​ ​important​ ​when​ ​you​ ​make​ ​measurements. Scientists​ ​use​ ​the​ ​term​ ​significant​ ​figures​ ​to​ ​refer​ ​to​ ​the​ ​digits​ ​in​ ​a​ ​measurement.​ ​The significant​ ​figures​ ​in​ ​a​ ​measurement​ ​include​ ​all​ ​of​ ​the​ ​digits​ ​that​ ​have​ ​been​ ​measured​ ​exactly, plus​ ​one​ ​digit​ ​whose​ ​value​ ​has​ ​been​ ​estimated.​ ​When​ ​you​ ​add​ ​or​ ​subtract​ ​measurements,​ ​the answer​ ​can​ ​have​ ​only​ ​as​ ​many​ ​figures​ ​after​ ​the​ ​decimal​ ​point​ ​as​ ​the​ ​measurement​ ​with​ ​the fewest​ ​figures​ ​after​ ​the​ ​decimal.​ ​When​ ​multiplying​ ​or​ ​dividing,​ ​the​ ​answer​ ​can​ ​have​ ​only​ ​the same​ ​number​ ​of​ ​significant​ ​figures​ ​as​ ​the​ ​measurement​ ​with​ ​the​ ​fewest​ ​significant​ ​figures. Percent​ ​error​ ​calculations​ ​are​ ​used​ ​to​ ​determine​ ​how​ ​accurate,​ ​or​ ​close​ ​to​ ​the​ ​true value,​ ​an​ ​experimental​ ​value​ ​really​ ​is.​ ​To​ ​calculate​ ​percent​ ​error,​ ​use​ ​the​ ​following​ ​formula: Percent​ ​error​ ​=​ ​ ​experimental​ ​value​ ​ ​-​ ​ ​true​ ​value​ ​/​ ​true​ ​value​ ​ ​X​ ​ ​100% A​ ​low​ ​percent​ ​error​ ​means​ ​that​ ​the​ ​result​ ​you​ ​obtained​ ​was​ ​very​ ​accurate.​ ​A​ ​high percent​ ​error​ ​means​ ​that​ ​your​ ​result​ ​was​ ​not​ ​very​ ​accurate. There​ ​are​ ​several​ ​ways​ ​to​ ​calculate​ ​an​ ​“average.”​ ​They​ ​include​ ​the​ ​mean,​ ​median,​ ​and mode.​ ​The​ ​mean,​ ​or​ ​numerical​ ​average,​ ​is​ ​calculated​ ​by​ ​adding​ ​up​ ​all​ ​the​ ​numbers​ ​and​ ​then dividing​ ​by​ ​the​ ​total​ ​number​ ​of​ ​items​ ​on​ ​the​ ​list.​ ​To​ ​calculate​ ​the​ ​mean,​ ​use​ ​the​ ​following formula: Mean​ ​=​ ​Sum​ ​of​ ​the​ ​numbers​ ​/​ ​The​ ​total​ ​number​ ​of​ ​numbers The​ ​median​ ​is​ ​the​ ​middle​ ​number​ ​in​ ​a​ ​set​ ​of​ ​data.​ ​To​ ​find​ ​the​ ​median,place​ ​all​ ​the numbers​ ​in​ ​order​ ​from​ ​smallest​ ​to​ ​largest.​ ​The​ ​median​ ​is​ ​the​ ​middle​ ​entry​ ​in​ ​the​ ​list.​ ​If​ ​a​ ​list​ ​has an​ ​even​ ​number​ ​of​ ​entries,​ ​add​ ​the​ ​two​ ​middle​ ​numbers​ ​together​ ​and​ ​divide​ ​by​ ​two.​ ​The​ ​mode is​ ​the​ ​number​ ​that​ ​appears​ ​most​ ​often​ ​in​ ​a​ ​list​ ​of​ ​numbers.
