Type I and type II errors

Edward Kaplan September 25, 2015 Descriptive statistics I can describe the data with the help of descriptive statistics. The data can be described with the help of various types of graphs and central tendency. Measures of central tendency are mean, median and mode. Mean is reliable for normal data. Median is reliable for a data which has outliers. And mode is preferred when data is categorical. There are various types of graphs like pie chart, bar graph which gives us a pictorial…

Movement& Response Time in Decision-Making Tasks I. Question 3: (i) Why are multiple repeated trials in each task required (ii) Why do we need to complete checks on the data (identify errors etc)? (iii) Why was there a variable fore-period between the start of a trial and the appearance of a stimulus in the tasks? (iv) Why was randomization necessary from Task 1b onwards? (v) Why was 80%(congruent) vs 20%(incongruent) split used in Task 2? II. Background (i) The importance of investigating…

determines blood type, whether it be A, B, AB, or O. This gene determines what type of antigen protein (if there is any in the first place) is attached to a red blood cell’s membrane. The gene is designated as I, and it has three common alleles, which include IA, IB, and i. Different combinations of these three alleles produce four different phenotypes, more commonly referred to as Blood Type A (homozygous IAIA or heterozygous IAi), Blood Type B (homozygous IBIB or heterozygous IBi), Blood Type…

was a two-part experiment meant to have us practice our skills and then use those skills in actual data collection and analysis. In part one we used a sample of sodium saccharinate combined with a sample of a metal halide salt, our group used copper(II) chloride. The combination of these two samples allowed for the synthesis of a metal complex. In part two of the experiment we used a procedure similar to part one in order to collect phosphorus out of a sample of fertilizer. This sample was then…

community college in Kentucky, as long as they both have proctored midterm. I would use a stratified sampling method to collect samples of 50 college algebra students midterm scores from 6 different community…

Both types of Fuzzy-GA models result in an effective prediction of P solubilization as shown in the Fig. 4. Though the performance of Mogul approach based Fuzzy-GA model is better than the Thrift approach based Fuzzy-GA model which is obvious from the visual representation in Fig. 4 (a) compared with Fig. 4 (b). Further, computed values of RMSE and correlation coefficient for two Fuzzy-GA methods confirm the better performance of Fuzzy-GA-I compared to the Fuzzy-GA-II. In case of Fuzzy-GA-I, the…

RFID TECHNOLOGY Radio-frequency identification (RFID): RFID Technology is a wireless electromagnetic field that is used to transfer data, or to identify people or objective, for the purposes of automatically identifying and tracking tags attached to objects. RFID is very fast, reliable and does not require any physical sight or contact between reader and scanner and the tagged items. There are some tags contains electronically stored information. It refers to small electronic devices that…

The values for the Axial length and Keratometry obtained through the various methods as mentioned above should be consistent so as to rule out sources of error. The need to repeat these measurements can be obtained based upon the HOLLADAY CRITERIA which states: Repeat Km if: Km47D for either eye Difference between the two eyes >1 D Corneal cylinder doesnot correlate well with the refractive cylinder Repeat AL if: AL< 22mm AL> 25mm Difference between the two eyes > 0.3 mm Doesnot…

programming paradigms and the features with the purpose of determining the suitability and applicability of the languages for each criterion, distinguish them with their pros and cons, evaluate and explore the related features on those languages. For this I have selected one language from each programming paradigm (imperative, object-oriented, functional, logic) and compared it with the Iterative statements feature. The comparing and contrasting is based on the following design characteristics:…

Participants and Procedures Acknowledging that drawing a sample from the general population may be impractical, costly, and time consuming the study will seek to obtain a representative subset (sample) of the population to investigate and make generalizations about the link between the categories of citizenship norms and the utilization of ICTs to politically engage. The population of interest consists of U.S. citizens aged twenty to thirty years old. The group was chosen to avoid any age…
