III. Identify statistical tools and methods to collect data:
A. Identify Appropriate Family and Reason for Selecting it.
To analyze A-Cap Corporation’s data, I will use measures of central tendency and distribution. Measure of central tendency is a measure used to describe the mean, median, and mode of a particular set of data while measure of distribution shows the skewness, kurtosis, and develops a hypothesis about a particular set of data. The reason I selected these two measures is that they will help analyze the data of A-Carp Corporation accurately.
B. Identify the Categories of Data and their Relationship with the Tools of Data.
The data in the case comprises of mean, standard error, median, mode, standard deviation, variance, skewness,…
from each other, and within each sample, the observations are sampled randomly and independently of each other.
2. The visual interpretation of the histogram is that there is a positive kurtosis and a negative skewness.

AGE is a categorical variable, which signifies that mode will be an appropriate measure of central tendency. The mode for the variable AGE is 1, which signifies that majority of the respondents fall in the age group of 18-35 years.

Outliers can be unusually minimum or maximum value while compared with the rest of the data set.
The median is the middle value of a set of data containing an odd number of values, or the average of the two middle values of a set of data with an even number of values. The median is especially helpful when separating data into two equal sized bins.
Another typical case when mean would not be a useful measure of central tendency is when the data is skewed. A distribution, or data set, is symmetric…
from -.80 to -1.14. While the kurtosis value for video threat was not noteworthy, it was nonetheless positively skewed as is evidenced especially by its histogram (see Figure 1). On the other hand, experienced tension-anxiety before and after viewing the video were more positively skewed as is also evidenced by their respective histograms (see Figure 2 and 3). Tension-anxiety before had a skewness value of 2.18, making its distribution non-normal given that the value is just outside of the +-…
Through reviewing the minimum, maximum, and range of values I attempted to discern and identify potential coding errors as well as invalid data. The nature and distribution of the values were explored through examining the mean, standard deviation, and variance as well as skewness and kurtosis. For example, the variable Age contained 320 valid cases, with respondents ranging in age from 18 to 35 years. The mean age was 28.02 years with a standard deviation of 4.76 years. Emailtime and Wwwtime…
Question 2: Discussion
For the first group of participants who cannot identify hypertension lifestyle factors and willingness to engage in self-care scores there are a total of 14 participants. The levels of central tendency consist of the mean of 5.5 which is the average score, the median of 5.5 which is the exact middle number and the mode of 7 which is the most frequent occurring score (Salkind, 2013). There was an average deviation from the sample mean of 2.35, therefore it can be said…
For example, the data in the Chamorro-Premuzic.sav file can be evaluated in a number of ways, for example analyzing the data based on the gender grouping allow one to visualize the data by manipulating the data using gender as a factor, then placing the remainder of the values as dependent variables. Evaluating the data in this way gives the investigator a better understanding of how the data is either normally distributed or perhaps skewed (Triola, 2008) .

The introduction of the article opened with a statement that racial privilege still exists in America. Phillips and Lowery (2015) identify Caucasians as the most privileged of all races. They claimed that whites had better earnings (Hao, 2011) greater life expectancy (Bleich, Jarlenski, Bell, & LaVeist, 2012) better access to health care (Smedley, Stith, & Nelson, 2003) and high-quality education (Rumberger, 2010) than other races, specifically African-Americans. As a result of their view of…
The experiment began with a reaction of a 1cm3 cube of lamb liver and 5mL of hydrogen peroxide solution being put in test tubes in a beaker filled with 10℃ water until the temperatures of the liver and hydrogen peroxide were 10℃ also. The liver was put into a 100mL measuring cylinder and the hydrogen peroxide was also poured in as the timer was started. After twenty seconds, several millilitres of froth had been produced from the chemical concoction. This froth was recorded into a results table,…
