Sample size

experimental group must be exposed to the treatment, or the independent variable. My true experiment to test whether art therapy programs for serious violent and chronic juvenile offenders is effective in reducing recidivism of offenders involves a sample size of 100 juvenile offenders, all with similar release dates. Using the probability sampling tactic of…

The article by Connor, Futh, Matias, & Scott attempts to show the relationship between attachment-based parenting measures and social learning theory-based measures in determining a child’s security of attachment to their care giver and social acceptance amongst their peers. The nature of the research conducted in this article was micro and exploratory because the researchers where looking to find a relationship between the two theories and children’s attachment style and social acceptance. The…

satisfaction and findings from representative sample for Secret Recipe to access consumer’s perceived quality. By using quantitative methods, the outcome produced are easier to summarize, make comparison and generalize from a larger sample population (Wyse, 2011). To measure the degree of overall consumers’ satisfaction, a survey method will be adopted. A recent research by Nawaz et al. (2013) uses self-administered questionnaires to gather responses from the sample. In addition, closed- ended…

from different locations. The scientists collected samples from seals inhabiting six different Hawaiian Islands. The first short tandem repeat primer revealed that three genes had variability. From these three loci the scientists focused on one locus, Hg6.3, because it was the easiest to examine. They still examined the other two loci, but gained limited data from them. To analyze the seal samples, the researchers extracted DNA from the samples and amplified the short tandem repeats using PCR.…

(Only continue if the relationship is significant) Step 2 – strength of association * Measured by the multiple correlation coefficient (coefficient of determination), R^2 * Adjusted R^2 takes the number of IV’s and sample size into account (can compare to different samples) * R^2 shows the predictive accuracy (if you can predict DV perfectly R^2 will be…

The first stage is called pre-sampling. What pre-sampling involves is the partitioning of records and the calculation of the right sample size. A study was conducted where 12 of the largest municipal police departments in the state overtook the population of this study. The population of all these cities combined came out to 285,898 and the number of incidents that were reported and recorded…

that the standard particle filtering method suffers from weight degeneracy especially when the estimation includes static parameters. EnKF, however, does not suffer from degeneracy and provides a good estimate of the coefficients by integrating a sample minimum mean square estimate (MMSE) of the coefficients within the EnKF algorithm. Without loss of generality, let us consider a first-order wide-sense stationary autoregressive state equation given by egin{equation} x_n = a x_{n-1} + u_n…

ADC works from few M samples to more than hundred of M samples with resolution from 8 bit to 16 bits. Due to its high resolution and sampling rate range it is widely used in medical and communication applications like as CCD imaging, base station, ultrasonic medical imaging, DSL, cable modem, digital receiver, digital video (HDTV) and fast Ethernet [79]. Fig. 4.5. Block diagram of a pipelined ADC Figure 4.5 Shows the complete architecture of the pipelined ADC. A sample and…

The article I chose was “SmartStretch™ Technology. I. Improving the tenderness of sheep topsides (m. semimembranosus) using a meat stretching device” (Meat Science 91 (2012) 142-147). The goal of this experiment was to see whether SmartStretchtm can improve hot-boned mutton tenderness. SmartStretchtm is a device developed by Meat & Livestock Australia and Meat & Wool New Zealand with the goal of preventing the muscular contraction of a boneless piece of meat by stretching it The animals used in…

barcoding experiment is to help collect and analyze sequenced data from the organism (plant or animal), use the extracted DNA to identify the species, and categorize the species, finding a relation between other organisms. Therefore, if an unknown sample has its DNA extracted following compatible protocols, then a matching sequence would appear, indicating identification when analyzing on a…
