$ have decided to do m& pro'ect on the topic: modelin" the temperature or seven dierent
cities $ have picked various cities across the "lobe or m& statistical pro'ect randoml& $ have
started recordin" the temperature o various cities at seven dierent points on the "lobe $
chose this topic to check %hether there is a model euation or the temperature chan"es
across the "lobe $t %as interestin" or me to ind that all m& "raphs sho%ed either a cubic or
uartic shape o the curve, %hich actuall& surprised me $ had done correlation and re"ression
to check the linearit& o the euation but mostl& it is not a positive one So $ had tried doin"
C($C re"ression or m& curve o best it hen to check i the population bet%een the
temperatures %ere eual or not $ have carried out the one-%a& anova i it is used to i"ure out
i there are an& note%orth& contrasts bet%een the means or three or more independent
"roups Conseuentl&, the h&pothesis is accepted, %hich e7presses that the population means
are all euivalent here %as not much contrast in the means or the temperatures $ there is
an euation ound like this then $ think the uture predictions o climate shit can be ound
%ell in advance
$ am "oin" to collect temperatures o seven dierent cities rom dierent time 8ones $
proceeded %ith m& pro'ect %ork throu"h the belo% sta"es:
