Many people believe that they have some form of psychic abilities including: telepathy, clairvoyance, etc. For our first experiment we will be testing psychic abilities depending on the ability to read symbols on a card which was not visible to the partner. For the second experiment we will be testing to see if quartz crystal can change the recessive mutation of flies. Quartz crystals are often found to possessed powers that could help heal illness. In this part of the lab we will est.. This hypothesis. For the third experiment we will be testing to see if we can see the relationship to a persons day based on their horoscope. The 8 different zodiac signs each correspond to a persons date of birth. So we test to see if the persons future was already written in the stars. Methods In experiment one there were 5 symbol, each on five cards, on a total of 25 cards. The person is essentially guessing which symbol is represented on the card. If we look at this experiment logically then they, the person guessing, has a 1 in 5 chance in guessing the card correctly, so the average person has a 20% hence of success in this experiment, taking in the probability of a false positive. In experiment two, the study was conducted from 8 cultures of vestigial flies. Four cultures were placed close to the quartz crystal with the healing power, which were the treatment group. The other four cultures developed with the absence of mediation and quartz crystal, which were the control group. All the adults in these cultures were removed and all that was left was he larvae which were allowed to develop. Data was collected from a squarer with the formula In experiment three eight paragraphs, describing peoples days were typed n cards, each one labeled with a letter. Eight horoscopes, from an astrologer matched to the day it was written, and the appropriate zodiac sign. Data was collected on the amount of matches, incorrect matched and the total attempts. If the average person were guessing they would have a 1 in 8 chance at success. Results For experiment one, the data that was collected was that the viewer guessed 7 out of 25 matches, which was higher than the average viewer guessing 5 out of 25 therefore showing that viewer had little to no psychic ability. Experiment two: This shows the EX. Contingency table which can be used to induct a chi-square test of independence, to see if the chance of being cured/ normal is independent of whether the fly was in the control group or the crystal group. Hauser: (n(ad x ((a+b)(c+d)(a+c)(b+d)) the results show: (n(xx -xx 6. 23. This data shows that there is no correspondence of the quartz crystal to the recessive mutation of flies. Observed vestigial X group = 10 Observed normal X groups =15 Total X flies= 25 Observed vestigial Y group = 12 Observed normal Y groups =13 Total Y flies= 25 Total vestigial flies-22 Total normal flies=28 Total flies-50 For experiment three: This table is expected t o show if the horoscopes be matched to the predictions more often then one would predict by chance. Total number of matches=3 observed accurate=14 expected accurate=2 observed inaccurate matches=28 Expected inaccurate= 12 Discussion: In experiment one the hypothesis was about whether a set of cards could predict psychic ability, although for the average person guessing there is a 1 and 5 chance of success. However, the viewer guessed 7 out of 25 which is hardly any greater than the mere 20% of the average person. In conclusion, if we are going y the hypothesis would conclude that a set of cards could possibly show psychic ability but this viewer has little to no ability. In experiment two the hypothesis contested that quartz crystal has some healing powers. In order to achieve this conclusion physical proof is needed. The physical proof in this experiment is if the healing powers of the quartz crystal will cure the flies of a recessive mutation. The data concluded that the quartz crystal indeed did not heal the flies of the recessive mutation. In experiment three: the daily horoscopes is said to have a correspondence teen the events of a persons day and their horoscope for that day. In this experiment, there were eight journal entries that one needed to be matched with the correct zodiac sign. With the data correlated it shows that number of matches has nothing to do with the zodiac sign and the journal entries. In conclusion, all of these hypothesis tested were concluded to all be false. These experiments show that no experiments can show psychic ability and that a future is not held in the stars but in life itself.
