Instruction: Qualitative Validity and Reliability Qualitative Data Collection.1. Throughout the article, the authors establish qualitative validity and reliability through the use of a historical perspective which is heavily laden with statistical information. These statistical information and their historical perspective lay a firm foundation for the proper evaluation of the research article on homeless women with preschool children. Additionally, the sampling choices consisting of two groups of different environments ensured that the research was presented with a case that covered all the possible environments, thereby resulting in a more reliable representation of the issue under research (Creswell 2013, pp. 188). This was further augmented through the use of focus groups as a data collection mechanism, which helped ensure reliable data consequently improving the validity and reliability of the research holistically . 2. The qualitative article primarily uses focus groups to collect the data used in the research article. This is whereby the researchers come up with a conducive setting and ensure that the sampled individuals feel safe about giving out as much information about the topic as possible (Averitt 2003, pp. 85). The safety and confidentiality associated with such focus groups ensures that the data is as reliable and valid as possible. Moreover, the researcher gets to interact with the sample in such a way that he/she experiences the effects of homelessness in the context that it is presented. Women for the focus groups were selected from the two identified shelters based on their adherence to a criteria that filtered them based on having at least one preschool child. These sessions are then recorded, and this is what constitutes the data collection mechanism for the qualitative research.References.Averitt, S.

Strongest and Weakest Parts of a Magnet

Strongest and Weakest Parts of a Magnet Did you know that the magnetic field of a magnet is not uniform? The strength of the field varies depending on its location around the magnet. The magnetic field of a bar magnet is strongest at either pole of the magnet. It is equally strong at the north pole when compared with the south pole. The force is weaker in the middle of the magnet and halfway between the pole and the center. If you were to sprinkle iron filings on a piece of paper and place the magnet beneath it, you could see the path of the magnetic field lines. The field lines are closely packed at either pole of the magnet, widening as they get farther from the pole and connecting to the opposite pole of the magnet. The magnetic field lines emerge from the north pole and enter the south pole. The magnetic field gets weaker the farther you get from either pole, so a bar magnet is only useful for picking up small items over short distances. Where Is the Magnetic Field Strongest? Iron filings make a pattern tracing field lines because each bit of iron is itself a tiny dipole (the separation between magnetic fields). The force the dipole experiences is proportional to the strength of the dipole and proportional to the rate at which the magnetic field changes. The dipole tries to align itself with a magnetic field, but at the ends of a bar magnet, the field lines are very close together. What this indicates is that the magnetic field varies strongly over a short distance compared to the variation closer to the middle of the magnet. Because the magnetic field changes so dramatically, a dipole feels more force.
