deviation of 16 and a mean of 16. This gives a psychologist a system of classifying whether participants are intellectually deficient or intellectually superior i.e. 70< Intelligence Quotient >130. This is similar to the rule of 68-95-99.7 which states that about 68% of the scores lie within one standard of the mean implying that 100% - 68% = 32% of the scores are more than one standard deviation from the mean. By the use of the 68-95-99.7 rule, a researcher can be able to state that about 68 percent of a population have an intelligence quotient score of 80-120, while 32 percent have an intelligent quotient of 70 to 110. Intelligence varies among different people, but the most important...

deviations of the mean, 95% are within two standard deviations of the mean, and 68% are within one standard deviation of the mean. This is an important consideration when manipulating and interpreting the collected data. The paper indicates that the latency was longer in the swearing condition relative to the non-swearing condition. In this case, the median heart rate for males in non-swearing condition was 85 while that of their female counterparts was 50 for the same conditions. These figures increased to 130 and 75 for the males and females respectively in swearing conditions. In essence, the results showed that cold pressor latency had a significant effect with F(1,69) = 26.942, P < .001....
deviation, s, for Miles_1 using Range/6 = 996/6 = 166 How close is this estimated s to the actual standard deviation of Miles_1: Estimate s.d./Actual s.d. = 166/97.71 = 1.7 Suppose a student has the Distance of 40. Use the Empirical Rule based on the information of ‘Miles_1 variable to decide if this is an unusual Distance or not. The standard deviation is 97.71 while the mean is 107.98. A distance of 40 miles is within 1 standard deviation of the mean to imply that it falls within 68% of the collected values. This is not an unusual distance. (d) Suppose a student has the Distance of 300. Compute the corresponding Z-score and using the Empirical rule to decide if this is an unusually far distance...

deviation=500 By using the 68-95-99.7 rule, nearly 68% of the light bulbs have a life time between: Mean- standard deviation=2500-500 =2000 Mean+ standard deviation=2500+500 =3000 An approximate number of 95% have a life of between Mean-2 standard deviations =2500-(2*500) = 1500 and Mean+2 standard deviations=2500+ (2*500) =3500 95.7% of the bulbs have a life of between Mean-3 standard deviations=2500-(3*500) =1000 and Mean +3 standard deviations=2500+3 standard deviations =2500+ (3*500) =4000 This means that 49.85% (95.7%/2) of the bulbs have a life that is inferior to 2500 (mean) Z-score = value – (Mean / SD) =2500-2500 500 =0 From the z table 50% is...

deviation, and so on. Tables, pie charts, and graphs can also be used to present the findings. Discussion At the completion of the experiment, the investigator should make a detailed observation and analyze the findings of the experiment. At this point, the investigator should answer the following questions. Do the findings support the hypothesis? Does the investigation require more research to be carried out? Besides, he or she can point out errors in the experiment. Conclusion The conclusion answers the investigator’s hypothesis as briefly as possible. It is because the answers have already been explained in the discussion section in detail. The investigator should also leave some...

deviation. The highest level has a mean of 3.67 and it is followed by 3.87, 3.79 and 4.01, in level two, three and four, respectively. Through this table, is clear that the standard deviation is directly proportional to values of the mean. The Estimated Marginal Means of Measure, as depicted by the graph, showcases the Estimated Marginal Means (y-axis) against the ‘remember’ x-axis. The 3.5 Estimated Marginal Means of Measure (y-axis) figure is the lowest one while 4.0 is the highest. These two figures are against 1 and 4 under the ‘remember’ x-axis, respectively. These statistics are requisite in recalling the facts and basic concepts of course material. The letter ‘N’ with a value of...
