 Ancient Greeks  Position of sun, moon, and planets  Possible influences/not the future  Phone and facebook apps, websites, newspapers, etc.  LA Times, Psychic Linda Black  Rate each day on a scale of 1-10 and give prediction Linda Black

 Are all the different ratings from 4-10 equally likely to occur overall?  Does zodiac sign affect the rating?  Does zodiac sign affect which areas of life are of most concern?

Procedure and Variables  50 random numbers from 1 to 120  Choose the corresponding weeks from the horoscope archives and analyze  Test 1: used numbers 4-10  Test 2: used scale of very high (v) = 9-10 High (h) = 7-8 Medium (m) = 5-6 Low (l) = 4

 Test 3: used variables for area H = health/energy L = love S = social/friendships W = work/power M = money E = other emotions  Conduct Tests and Intervals

 Chi-Square Goodness of Fit Test  Conditions:  Categorical data --- Horoscope ratings are categorical  SRS random ratings  All cell counts > all exp. cell counts > 5 All conditions met >> χ² distribution >> χ² GOF test  Hypotheses: Ho: Ratings are uniformly distributed Ha: Ratings are not uniformly distributed + = P ( >352.2|df=6)=0.0001

 We reject the Ho because the p-value of is less than the alpha value of.05. We have sufficient evidence that ratings are not uniformly distributed.

 Chi-Square Independence test  Conditions:  2 Independent SRS--- yes, known  All cell counts > all exp. cell counts > 5 All conditions met >> χ² distribution >> χ² Independence test  Hypotheses: Ho: There is no association between sign and rating Ha: There is an association between sign and rating =37.38 P( >37.38|df=33)=0.27

 We fail to reject the Ho because the p-value of 0.27 is greater than the alpha value of.05. We have sufficient evidence that there is no association between sign and rating.

What’s your sign’s mean rating?

 Chi-Square Independence test  Conditions:  2 Independent SRS--- yes, known  All cell counts > all exp. cell counts > 5 All conditions met >> χ² distribution >> χ² Independence test  Hypotheses: Ho: There is no association between sign and area Ha: There is an association between sign and area =32.04 P( >32.04|df=55)=.99

 We fail to reject the Ho because the p-value of 0.99 is greater than the alpha value of.05. We have sufficient evidence that there is no association between sign and area.

 The ratings of horoscopes are not evenly distributed; they are quite inflated toward the positive side  Each sign has a different “personality”, but that does not warrant for an association between sign and rating  All because one is a specific sign, they cannot expect more horoscopes based upon a certain genre

 Some could have discrepancies with our scale of goodness; very high (9-10), high (7-8), medium (5-6), and low (4)  Areas fall under two categories  No days below a “4”

 We don’t believe in horoscopes  No rating below 4, don’t want to give people negative days  Claim that each zodiac sign makes a person different, but according to this study, all areas of concern and daily ratings are roughly the same
