Discussion1minitab Express Is A Very Helpful Descriptive Statistics T

Discussion#1 Minitab Express is a very helpful descriptive statistics tool that can be used in research to calculate and provide outcomes pertaining to the research data gathered. According to Divisi, Leonardo, Zaccagna, & Crisci (2017), statistical concepts such as the mean, median, and mode along with frequency distributions can be graphed and further explained. The mean, median, and mode are known as the measures of central tendency. The mean is the average, the median is the numerical data in the exact middle, the mode is a value that occurs most frequently, and the range is the distance between the highest and lowest value (“Measures of Central Tendency,” n.d.). When a research study is supported by numerical evidence, it proves validity and receives recognition by the community (Divisi et al., 2017).

Using Minitab Express was an interesting experience. I was very thankful to know that there is a program that can assist with the statistical analysis of data. I honestly knew nothing about this until I entered week 9 of this class. It is fascinating to know that once the data is entered, graphs can be made, measures of central tendencies found, and an explanation given. According to Connor & Johnson (2017), descriptive statistics summarize, analyze, and describe data in ways that make the information easier to understand.

When evaluating the information given in the discussion, with different ages and levels of mathematical anxiety, I found that the mean age was 36.2 and the median was 33.5 with a standard deviation of 11.232. The mean number of individuals that felt uneasy was 3.7 with a standard deviation of 1.3018 and the median 4.0. These statistical analyses were completed for each level of mathematical anxiety. According to Niles (n.d.), the closer the standard deviation is to the mean, the more clustered the data is surrounding the mean. When examining the anxiety category of feeling afraid, the mean was 3.55 and the standard deviation 1.1459.

The standard deviation in the category of afraid was the lowest, meaning that the data in this category was clustered closest to its mean. When evaluating the mean of each category, the category with the highest mean was uneasy, and the lowest mean score was found in the category of feeling worried. Discussion Question Part 2 I plan on learning more about descriptive statistical analysis and utilizing the Minitab Express program through practice. It is important to understand the mean, median, and mode along with frequency distribution and other statistical concepts (Divisi et al., 2017). I believe that Minitab Express and other statistical analysis programs will allow the researcher to further their knowledge on the data collected by assisting in providing graphs and statistical analyses.

Testing the Minitab Express program furthered my knowledge of understanding data. It was informative to have hands-on experience and the ability to view the results with explanations. If becoming proficient in descriptive statistical analysis becomes part of my everyday routine, I would take a class to better understand the functions of the different programs. Discussion #2 Excel descriptive statistics is an excellent tool for organizing data analysis research. Excel can provide a more efficient way to demonstrate the data analysis skills component of the research process (DiMaria-Ghalili & Ostrow, 2009).

In order to organize the information, there are columns and rows present on the spreadsheet. The Excel program can perform several statistical functions including charts, graphs, and equations to help determine data in research studies. In the beginning, I thought the descriptive statistics was too complicated. Once I learned the techniques, my experience running descriptive statistics was smooth. This makes it easier to analyze the measure that reflects math anxiety and the study variables.

The data shows that the mean of age was 36.2 with the use of descriptive statistics. I could plug the given information and was able to make two simple histograms of two different variables such as a histogram of cringe and histogram of uneasy. I would like to learn more about Excel and more specialized statistical software packages including SPSS and SAS. It is important to learn more informatics skills in statistics. The information I learned about Excel descriptive statistics will be very useful in future analysis of research data.

There are a variety of methods, such as correlations, regressions, two-sample analysis, and probability distributions, available in this software to analyze the data. This is very relevant for future research data analysis. Choosing appropriate statistical tests and correctly performing basic statistical analysis and interpretation of output are all possible with Excel (DiMaria-Ghalili & Ostrow, 2009).

The use of statistical software tools like Minitab Express and Excel has revolutionized research data analysis, making it more efficient and accessible for researchers across disciplines. These tools facilitate the computation of essential descriptive statistics such as the mean, median, mode, and standard deviation, enabling researchers to comprehend complex data sets with ease. Understanding these statistical concepts is vital because they form the foundation for data interpretation and validation, as emphasized by Divisi et al. (2017), who highlight the importance of graphical representation and statistical summaries in analyzing research data.

Minitab Express stands out as a particularly useful program for conducting descriptive statistical analysis due to its user-friendly interface and robust functionalities. It allows researchers to enter raw data and automatically generate appropriate statistical measures and visualizations. For example, in analyzing data related to mathematical anxiety and age, the software provides insights such as mean ages, variability through standard deviations, and the clustering of responses around the mean. The findings indicate that the mean age of participants was 36.2 years, with a standard deviation of 11.232, illustrating a moderately dispersed age distribution. Similarly, measures related to anxiety levels, such as feelings of unease and worry, demonstrated varying degrees of clustering, with the anxiety of feeling afraid displaying the lowest standard deviation, signifying responses were more closely aligned.

Furthermore, employing descriptive statistics enhances the understanding of research variables and their distributions. The analysis revealed that participants generally reported higher mean scores for feelings of unease compared to worry, suggesting that anxiety related to mathematics manifests more as discomfort or distress rather than outright worry. Such insights are crucial for tailoring interventions in educational or psychological contexts. The ability of Minitab Express to produce clear, interpretable graphs complements numerical summaries, providing a comprehensive view of the data landscape.

Parallel to Minitab Express, spreadsheet software like Excel offers accessible tools for preliminary data analysis. Its intuitive interface enables researchers to organize data efficiently and perform basic statistical functions, including histograms, means, and standard deviations. In my experience, once familiar with the techniques, running descriptive statistics in Excel became straightforward. Creating histograms of variables such as cringe or unease helped visualize the distribution patterns, clarifying how responses clustered around certain values. While Excel lacks the depth of specialized statistical software, it remains a valuable tool for initial analysis, especially when resources are limited.

Expanding proficiency in statistical software, including programs like SPSS and SAS, is essential for conducting more complex analyses such as correlations and regressions. These tools offer advanced functionalities, enabling researchers to explore relationships between variables and perform predictive modeling. As DiMaria-Ghalili and Ostrow (2009) emphasize, proficiency in these programs improves the accuracy and interpretability of research findings. Moreover, mastering a range of statistical tools equips researchers to handle diverse data types and methodological approaches, ultimately strengthening the rigor of their studies.

In conclusion, integrating software like Minitab Express and Excel into research practices significantly enhances data analysis capabilities. While Minitab provides comprehensive statistical summaries and visualizations, Excel serves as a practical starting point for organizing and interpreting data. Developing skills in these programs, along with advanced tools like SPSS and SAS, facilitates precise and insightful analysis, advancing research quality and contributing to evidence-based decision-making.
