Copper-alloy miniature votive dagger. The pommel is uneven and spherical with a ridge at the top. The pommel narrows into the slightly curved grip. The guard is a square shape with two parallel grooves on each side. The blade narrows into a dulled point. There is a round hole three-quarters of the way up the blade. The back is chipped on the left edge of the blade near the point (as seen in figure 1) and has furrows on the blade below the hole. The front has scratches on the blade above both…

In general, the experiment succeeded in demonstrating free-fall by dropping a tennis ball. Distance and time were documented to calculate velocity and acceleration, the quantities involved in linear kinematics. Graph 1 (distance vs. time) suggests a commonsensical relation - longer distance yields longer time. The only exception is at 1.0 m, where its time value (0.42 s) is less than that of a shorter distance (0.5s for 0.5 m distance). Average time was used to construct the graph, and there…

To do this experiment you will need two subjects that have different arm lengths. In this experiment Subject 1 had an arm length of .81 meters and Subject 2 had an arm length of .77 meters. It is crucial that the subjects have different arm lengths because if they don’t your results will be invalid. The first step in this experiment is to set up the camera using the tripod and insert an SD card. Next, position the camera perpendicular to the sagittal plane along the x-axis in regards to the…

Laboratory Exercise 1: Anatomy Lab Report Scientist: Eryka Ocasio Ramos Lab Title: Scientific Method and Measurements I. Problem: Is there a correlation between the length of the upper and lower limbs and the height of an individual? II. Hypothesis: The length of a person’s upper limb is equal to 0.4 (40%) of the height of the person. III. Variables: Independent Variable: The people chosen for the experiment. Dependent Variable: Height and upper limb length. IV. Constants: Units of measure, the…

taking the value of something. But what about value in people? I am fifty percent Hispanic. I am one half. I am more Hispanic than not, but I am less than hundred percent. If these statements coincide with the value of fifty percent, does this also mean I am incomplete? I am proud to be what I am. I am an American, but moreso, I am a person. I was born here, and I was raised here. I have a mixed background, but name one person in this room today who does not, because as far an anyone should be…

In the next step, the graded response IRT model will be analyzed again for each identified domain, but without the excluded items, and the model fit statistics will be assessed. If the model has a good fit statistics, the best item for each domain will be selected according to the distribution of the threshold values across the latent scale and the discrimination value; item that has threshold values cross the whole latent scale and high discrimination value will be selected. Sample Size Graded…

Variance refers to how far apart the data points are in relation to the mean. It is helpful when calculating the probability of future events. Standard deviation is a measure of how spread out numbers are and we use the variance of data to calculate it. In order to calculate the standard deviation you take the square root of the sample variance. The combination of standard deviation and mean will allow you to know the majority of data sample. It’s important to understand there is…

ii.) Do parents believe that the new middle school science club is worth the funds the district spent? This would be the most applicable of the following for a survey research topic. Because this topic focuses on the beliefs of parents, regarding their feelings and experience with the middle school science club, a survey can be used to assess their responses. The other three topics involve the type of research that would need to be conducted in more intensive qualitative and quantitative form,…

This study was conducted in Selale, one of the 18 zones of the Oromia regional state in Ethiopia. The research site is located between 37 and 100km Northwest of Addis Ababa. It has a high potential for rain-fed cereal and livestock production. The main food crops are barley, wheat, teff, beans and peas. Livestock is considered to be the main asset of the farming community. There are two cropping seasons in a year. The major cropping season is characterized by relatively high rainfall, starting…

Conducting a cost-benefit analysis involves a comparison of a project’s total cost and the aggregate benefits of the beneficiary population. In the aggregation process of benefits estimates, individual-level estimates – such as the sample mean or median willingness to pay WTP – are extrapolated to those population (Morrison, 2000; Bateman et al., 2006). This is a common practice, especially within choice experiments’ literature (CE) (Kopp et al., 1997; Breidert et al., 2006). The issue raised by…
