Some basic statistical jargons that you should be familiar at the beginning of any analysis are listed below:
Distinguish between population and sample
• A population is the entire group that you want to draw conclusions about. A sample is the specific group that you will collect data from.
• Your sample is the group of individuals who participate in your study, and your population is the broader group of people to whom your results will apply.
Descriptive statistics versus inferential statistics
• Descriptive statistics summarize the characteristics of a data set. Inferential statistics allow you to test a hypothesis or assess whether your data is generalizable to the broader population.
Qualitative variable versus Quantitative variable
• Data collected about a numeric variable will always be quantitative. Example age, income
• Data collected about a categorical variable will always be qualitative. Example gender (male and female), location (urban and rural)
Measures of Central Tendency
In statistics, “measures of central tendency” refer to statistical measures that aim to describe the center or value of a data set. These measures provide a summary of the data by focusing on its central location or average value. The three most common measures of central tendency are the mean, median, and mode.
Measures of Dispersion
In statistics, “measures of dispersion” refer to statistical measures that quantify the spread or variability of a data set. While measures of central tendency (such as mean, median, and mode) provide information about the central location of the data, measures of dispersion provide insights into how the data points are spread out or scattered around the central value. The most common measures of dispersion are range, inter-quartile range, variance, and standard deviation.
We will be exploring most of these basic statistical jargons in our upcoming SPPS webinar scheduled on this Sunday (25 June 2023). For details, please contact (i) nurshazwani_g@upm.edu.my, (ii) contact number: 60199154822
