Non-parametric statistics

Just Count The Pegs In “Just Count The Pegs” it told us to find the formulas of polygons for Justin, Sarah, and Flashy. It gave us simple information about each person and how to find the formula. Each person says they have their own formula. I used the books information to help me find the formulas. Justin Short says he has a new shortcut. His formula is like an In-Out table. For the In it is the number of pegs around the sides of the polygon. For the Out is is the total area of the figure.…

1. The pH of Welch’s Juice Significantly different than what I had hypothesized. I reject that part of my hypothesis because I feel like it was too far from what the actual number was. I had hypothesized 6 because I felt like the other parts of that solution would make it less acidic. I was wrong and the actual number was 3. On the other solutions I was exactly on or off by one number. 2. The pH range of my solutions were from 2.5-7.The most acidic solution I had was vinegar which had a pH of…

To begin with, the frequency tables show the number of participants and what they answered for both the scale of income and state of health can been seen in Figure [1] of the Appendix. There were 83,154 participants that responded to the wealth question [1] and 85,949 participants that responded to the health question [Figure 2]. For the wealth question, the frequency of the data from the respondents is skewed toward the First Step at 6483 people (lowest wealth), peaks toward the Fifth Step at…

the nondominant hand, we measured an average of 21.25 kg for maximum clench strength before fatigue, an average of 19.75 after fatigue, an average of 35.25 seconds for clench duration before fatigue, and an average of 29 seconds after fatigue. The statistics on collected data indicated that when it came to the maximum grip strength, there was no significant difference before or after the arm muscles had been fatigued, or between the dominant and nondominant hands. In addition, the results also…

look at those statistics and make a judgment about how they can relate or how they play into that statistic. What intrigues me is who comes up with those statistics? That is why I choose the career statistician to research about. Most people think having a career in statistics would be mind-numbing because you have to use math. This in most cases, math can be unexciting or dull. The reason using math for statistics can be enjoyable is quite interesting. I believe that statistics can relate to…

The purpose of this study is to evaluate the impact of interventions designed to reduce hospital admissions or length of stay amongst frail older people. Databases that were used to retrieve the studies are: PubMed / Medline, PsycINFO, CINAHL, BioMed Central, Kings Fund library. Studies were limited to publications from period 2007- present. Researchers classified interventions into those which aimed to prevent admission, interventions in hospital, and those which aimed to support early…

2. There is a good, positive correlation between the six variables in the HC scale. The Cronbach Alpha is .769. From looking at the Inter-Item Correlation if I delete any variable the Cronbach Alpha will go down so there is no need to delete anything. The SE scale Cronbach Alpha was .686, after looking at the Inter-item Correlation chart all of the variables were positive but there were a few variable that were low. If I was to delete any variable the Cronbach Alpha would decrease. So the…

Joseph performance on the attention tasks during this testing exhibited variability. Joseph’s performance on visual attention task was below the threshold of statistical significance; however, it did demonstrate subtle difficulties in the area of detectability, inattention, response speed consistency. He also made slightly more anticipatory errors than others in his age group. There was slight reduction of speed noted during the later blocks. His response speed also showed slight decrease when…

lot on how statistics is involved in our everyday life. We also have learned why statistic is useful in comparing things. In our book Naked Statistics by Charles Wheelan we read some chapters in where we use stats in three different ways to get close to the answer without using all the data. We see how indepednt variables and dependent variables relate to each other and how we can get close to seeing how close they relate without using the full data. Correlation is a form of statistics in…
