Generally, measures of dispersion report on how "noisy" your dataset is. Using the data from the Boiling Point Vs Number of electrons Noble gases table, plot a graph of boiling point versus number of electrons for the noble gases. The concepts and basic vocabulary of physical science and their application to life and work in contemporary technological society will be addressed when the unit is introduced through a concept change lesson. State a generalisation relating London dispersion forces to the number of electrons in atoms or molecules. Students will be able to: 1 Calculate measures of central tendency and dispersion for one variable data sets from a graphic representation of the data set, a table, or a context.

Average: It is a value which is typical or representative of a set of data. Averages are also called Measures of Central Tendency. Simple to calculate. It should be easy to understand. Rigidly defined. Based on all items of observation.

What is the median of the following set of scores? The denominator bottom of the z-score formula is a. The standard deviation b. The difference between a score and the mean c. The range d.

## Measures of Location and Dispersion and their appropriate uses

Quantitative data can be described by measures of central tendency, dispersion, and "shape". Central tendency is described by median, mode, and the means there are different means- geometric and arithmetic. Dispersion is the degree to which data is distributed around this central tendency, and is represented by range, deviation, variance, standard deviation and standard error. Richards, Derek.

Measures of location describe the central tendency of the data. They include the mean, median and mode. Their calculation is described in example 1, below. The median is defined as the middle point of the ordered data. It is estimated by first ordering the data from smallest to largest, and then counting upwards for half the observations.

The first exercise focuses on the research design which is your plan of action that explains how you will try to answer your research questions. Exercises two through four focus on sampling, measurement, and data collection. The fifth exercise discusses hypotheses and hypothesis testing.

*Variability refers to how "spread out" a group of scores is. To see what we mean by spread out, consider graphs in Figure 1.*

### Measures of Variability

- Мидж, - взмолился он, - я знаю, что ты терпеть не можешь Стратмора, но… - Это не имеет никакого значения! - вспылила. - Первым делом нам нужно убедиться, что Стратмор действительно обошел систему Сквозь строй. А потом мы позвоним директору. - Замечательно.

Директор, Стратмору не удается отключить ТРАНСТЕКСТ. - Что?! - хором вскричали Бринкерхофф и Фонтейн. - Он пытался, сэр! - Мидж помахала листком бумаги.

Он схватил парня за рукав. - У нее кольцо, которое принадлежит. Я готов заплатить. Очень. Двухцветный застыл на месте и зашелся в истерическом хохоте. - Ты хочешь сказать, что это уродливое дерьмовое колечко принадлежит. Глаза Беккера расширились.
