Preparation for Statistics Month Celebration

Arrangement of data into different classes or groups is called

• Statistical distribution

• Frequency distribution

• Econometric distribution

• Classful distribution

The variability of a set of continuous scores around the mean is indicated by the means of

• Variance

• Phi-coefficient

• Slope coefficient

• Standard deviation

The number of observations that falls in a certain class is known to be its

• Range

• Limit

• Rank

• Frequency

A normal distribution in kurtosis is named to be

• Leptokurtic

• Platykurtic

• Normal kurtosis

• mesokurtic

Statistics used to describe or summarize a set of observations is known to be

• Descriptive statistics

• Comparative statistics

• Referential statistics

• Inferential statistics

The mean is influenced by:

• The order of data

• Individual scores.

• Outliers

• The standard deviation.

Standard deviation tells you:

• 1. How spread out the data are.

• 1. How many outliers there are.

• 1. what the mean, median and mode are.

• 1. the square root of the mean.

You are given the following data set: 6, 3, 5, 2, 6, 4, 9.

Which of the following statements is NOT true about the data set?

• The mode is 6.

• The median is 5.

• The mean is 6.

• The range is 7.

Which of the following is not a measure of dispersion?

• 1. Range

• 1. Standard deviation

• 1. Variance

• 1. Median

Please describe the following type of data visualization:

• 1. This is a histogram and is used to represent linear data.

• 1. This is a radial tree and is used for geospatial mapping.

• 1. This pie chart is used to represent temporal data.

• 1. This is a pie chart and is used to represent proportions.
