1.5 Range, interquartile range and box plot | Basic Statistics | Exploring Data | UvA
Переглядів 10 тис.7 років тому
To describe a distribution you need more information than the measures of central tendency. You also need information about the variability (or dispersion) of the data. Matthijs discusses the (dis)advantages of two measures of variability: the range and the interquartile range. You also learn about the boxplot, a useful graph that gives a good indication of how the values of your distribution a...
1.6 Variance and standard deviation | Basic Statistics | Exploring Data | UvA
Переглядів 14 тис.7 років тому
This video discusses two other measures of variability that are often used in statistical studies: the variance and the standard deviation. You learn how to calculate the variance and standard deviation by hand (using a formula).
1.4 Mode, median and mean | Basic Statistics | Exploring Data | UvA
Переглядів 13 тис.7 років тому
Next to summarizing a distribution by means of graphs, it can also be useful to summarize the center of your distribution. In this video Matthijs discusses three main ways to do this: the mode, mean and median. You also learn when to use which measure of central tendency.

      @@dzulhajjaeynabesiregar3908 still yes that is the precise use of a poll it it’s to collect data for a quantitative nature and deliver the information to a user. It is a research tool. It is essentially a single question of a research survey. So yes if the only thing you want information on to quantify is a single question and not a multitude of them a poll is a good method of getting a multiple choice response.
