Descriptive Statistics Overpriced MyTab (H1) Central Tendency: Mean = 46.80 Dispersion: Standard Deviation = 11.86 per age group Number: 400 Min/Max: 27/58 Confidence Interval: (z) 36.40-57.20 Competitor has Better Products (H2) Central Tendency: Mean=33.20 Dispersion: Standard Deviation = 8.84 Number: 400 Min/Max: 21/45 Confidence Interval: (z) 25.45-40.95 Descriptive Statistics Interpretation Overpriced MyTab (H1) 400 participants were randomly selected to complete a survey that asks yes or no questions. They were divided into 5 categories depending on their age (18-45). The data was normally distributed as shown by the p-value of .05. There is a 95% confidence that there are 36.40-57.20 persons in each age group that responded that they believe the MyTab is overpriced. Competitor has better product (if applicable) This data was also normally distributed.
DESCRIBE HOW PERSUASION CAN INFLUENCE JURY DECISIONS Research has investigated the effect of having an expert psychologist who explains all the psychological variables that affect the accuracy of eye witness testimony which includes delay in identification, leading questions, weapon focus effect, feature and etc. overall eye witness will have an inaccurate or reconstructed version of the true event. Cutler aimed to investigate whether hearing about psychological research from an expert witness which casts doubt on the accuracy of eyewitness testimony would affect the jury’s decision. It was a lab experiment of 538 Psychology undergraduates whom were given extra credits. They watched a videotaped mock trial in groups.
Part 1 The table shows data from an experiment by social psychologist Stanley Milgram into levels of obedience to authority amongst 'ordinary' people. How would they behave in a moral dilemma between authority and wickedness? The headline row labels the 2 numerical columns directly below, which show the average level of shock administered and the proportion of participants who obeyed until the maximum voltage. The extreme left column labels pre-trial predictions, the original study and 2 variations. Row 1 shows that before the experiment students predicted a relatively low, (140v), level of shock would be administered and that none, (0%), would comply to the end.
Assess the sociological explainations of why girls acheive better results than boys (20 marks) There are many reasons why girls do better than boys in education . It is proven that boys mature later than girls and that girls are often ahead in language, it is said that at the age of 11 average boy is 9 months behind an average girl. Female expectation and behaviour also contribute to the fact that statistically girls are doing better than boys and I will now develop and assess some of these factors. Women expectations and plans for the future have changed over time. Sue Sharpe (1976) have carried a survey which led to her discovering that girls priorities were marrige and family over career and education however when repeated in 1994,
Age, Stress and Satisfaction with Life Differences Among People Who Have Morningness/Eveningness Preferences. Ayesha Riaz PSS110 Assignment 2 Student number: 9916911 Due Date: 28-04-2013 Tutor: Catherine Cornan Abstract There has been a lot of research done in the past on individual differences in chronotype. This study aimed to find differences in stress and satisfaction with life among people who have morningness or eveningness preferences. Data was collected through an online survey of 304 Psychology undergraduate students. Results of the study showed that older people scored higher on morningness than younger group and that morning type individuals had higher levels of satisfaction with life and lower levels of stress compared with the evening type individuals.
The aim of the experiment is to see if the chewing of gum improves memory and cognitive functions. It was hypothesised that those who chewed gum received on average a higher % score that those who did not chew gum. Method- Participants- 70 adults aged between 18-45 randomly allocated to partake in a test consisting of testing the popular theory of memory improvement from chewing gum. Materials- In this study, the following was used: 35 pieces of gum, paper and pencils and a list of the 15-20 words. Procedure- This investigation involved showing a population a list of 15-20
The anaerobic group presented a 24 percent reduction whereas the control group presented a 20 percent reduction in their symptoms of depression. One must remember these percentages are approximate values. Decreases in depressive behavior were calculated on the mean results of the three groups, whilst assessing any inconsistencies within the responses as they were measured in accordance with the individual group’s standard deviation. It was determined by Balkin, Tietjen-Smith, Caldwell, and Shen (2007) that the aerobic group gained the largest benefit whereas the controlled group gained the least (Balkin, Tietjen-Smith, Caldwell, & Shen, 2007). Reliability and Validity All three groups used a standard deviation as the determining factor for reliability.
A closer examination of the test shows that I have become twice the extrovert than 25 years ago. I do worry about unnecessary situations but I am compassionate and concerned for others (agreeable) and, yes, a disorganized person. The Jung and Briggs-Meyers typology test results reflect that I am an ISFJ: Introverted, Sensing, Feeling, and Judging. I scored a 75% on feeling and 22% introverted followed by sensing at 12% and judging 11%. A difference of the introvert and extrovert is shown between the two tests but both agree I rate highest in
One percent may not seem significant, but when there are approximately half a million people who die of a heart attack each year, this means 5,000 more people would be saved. According to Brophy and Joseph, "the probability of t-PA being clinically superior is at best 50-50," since t-PA's one percent better survival rate has a margin of error. They say that although t-PA might do better in 999 out of 1,000 trials, it would do approximately one percent better about half those times, at best. The article then raises the question
They found that participants remembered about 90% when there was only a second interval; but this dropped to 2% when an 18 second interval was emplaced. Thus concluding verbal repetition prevents rehearsal of items being stored in STM decay quickly, so items last approximately 10 seconds in STM without rehearsal. One research conducted by Bahrick et al in America demonstrated the considerable duration of LTM by asking people of various ages to put names to faces from their high school year book. 48 years on people were about 70% accurate. There was a free recall test, photo recognition test and name recognition test.
