important considerations, which a researcher should pay attention to. Reliability, in this case, can be described as the degree to which the data collection process is consistent. On the other hand, validity arises when variables measure what they were intended to measure. And, this, usually, happens when the data collection process has been reliable.
will determine why these disparities exist. This paper originates on information of data coming together between both groups. The central tendency, dispersion, and skew data will be examined. In order for the team to calculate the measure of central tendency we will measure an adequate sample or population that will represent a true mean. The measure of central tendency will
Probability & Measures of Central Tendency Part 1 The data collected for this paper will be the number of minutes spent on the commute to school each day for a ten day period. The commute is generally between 20 and 30 minutes, though traffic problems, particularly accidents, can greatly increase the time for the commute. Minutes Per Day Spent on Commuting EMBED Excel.Sheet.12 Part II Using the data you have collected in above, please do the following: Calculate the mean, median,
are measures of central tendencies and measures of dispersion. Measures of central tendency are “measures which are at the central position of the frequency distribution and which are representative of the whole distribution.” (Tanner, D. E., & Youssef–Morgan, C. M. , 2013) A part of the measures of central tendency is the mean, mode and median of the data for which was describe. Measures of dispersion are “measures that show how far the actual values are from the measure of central tendency.” (Tanner
be unnecessary, in the case of provinces, and illogical for the PES11_11, a scale variable (highest level of measurement). Since this is a scale variable, I was able to calculate all the measures of central tendency (measures that tell us the most typical values) and dispersion (how typical these typical central values are). These statistics are relevant to calculate because they allow for more meaningful calculations that allow us to draw more specific and accurate conclusions about claims such

available from medical coding systems at Royal Victoria Hospital. The sampling methodology used to determine these 35 patients was stratified sampling. According to, (Yin, 2003), with stratified sampling, the population is categorized in different layers known as strata. Each level consists of individuals with homogeneous characteristics. Once the layers are created, either simple random sampling or systematic random sampling is used to make a sample from each stratum (Yin, 2003).
detailed information on why these variables were included in the model. Data also has been described and reported by measuring central tendency of the data. A main descriptive statistics of the variables used in the model shown below. The descriptive statistics includes number of observation, mean, standard deviation and range. The most popular measure of central tendency is mean, which reports the average of variables. In this study mean represents an average value of each variable among 34 OECD
certain activities. Phosphorus is often associated with suspended solids, which have a significant relationship with turbidity. Strong relationship has been reported between turbidity and suspended solids, where turbidity has been used as a surrogate measure for total suspended solids (Acheampong et al. 2012; Packman et al. 1999). A consistent relationship has also been reported between total

Objectives of the Study • To find out the effect of packaging on the buying behavior decision. • To check the effect of packaging elements on the buying behavior. • To measure the relative impact of each packaging element on the consumer. • To identify the elements, which should be highlighted while design the packaging. 1.4. Justification The objective of this study is to determine role of packaging on consumer’s
