Reliability and Validity When examining the data they have collected‚ it is essential for researchers to determine to what degree is their data consistent. There are many methods by which researchers can assess the reliability of their instruments. Through different statistical procedures‚ researchers will evaluate the reliability coefficient to ascertain to what extent their data is consistent. The reliability coefficient is generally a numerical value between 0.00 and 1.00‚ where the coefficients

Before and After the Civil War The three different but similar events all had something in common for people’s equality. The 1st event that happened was the Sojourner Truth speech in 1815‚ at the Women’s Convention in Akron‚ Ohio and it was focused on women’s equality.

study. To ensure that this was achieved‚ the survey needed to demonstrate validity and reliability. Validity‚ as described by Heale and Twycross (2015‚ 66)‚ examines whether the specific concept has been accurately measured. In contrast‚ according to Floss (2013‚1)‚ reliability refers to the consistency of the instrument to measure the concept. The instrument needed to feature external validity in order for the data collected to be generalised (Heale and Twycross 2015‚ 66). To ensure the instrument

The measures of central tendency are simply a statistic used to present data in the form of averages. The most common measures of central tendency are the arithmetic mean‚ the median and the mode. The measures of dispersion tell you how widely spread out or scattered these values are. The range and standard deviation are two examples. Measure
