What is the synonym of summarize?
recapitulate. show the lay of the land. show the ropes. summarize. tip off.
How do you describe the spread of data?
Measures of spread describe how similar or varied the set of observed values are for a particular variable (data item). Measures of spread include the range, quartiles and the interquartile range, variance and standard deviation.
What is a single number that summarizes an entire data set?
In statistics, the mean summarizes an entire dataset with a single number representing the data’s center point or typical value. It is also known as the arithmetic average, and it is one of several measures of central tendency.
What are the 4 measures of central tendency?
The four measures of central tendency are mean, median, mode and the midrange. Here, mid-range or mid-extreme of a set of statistical data values is the arithmetic mean of the maximum and minimum values in a data set.

Which one is a strategy for summarizing?
Strategies for summarizing
When you summarize, you explain the main idea(s) from someone else’s work. Note that you must include citation information for summaries – think of your citation as showing your reader where they can find the original or “full” version of the work that you have summarized.
How do you describe the range of values?
The range is the difference between the highest and lowest values within a set of numbers. To calculate range, subtract the smallest number from the largest number in the set.
How do you describe the spread of a distribution?
The spread of a distribution tells you the range of your data. If your spread is small, then your data covers a short range. If your spread is large, then the data covers a larger range. For our donuts, a small range would mean that people cluster together with their choices being very close to each other.
How do you summarize data using descriptive statistics?
- Step 1: Describe the size of your sample. Use N to know how many observations are in your sample.
- Step 2: Describe the center of your data.
- Step 3: Describe the spread of your data.
- Step 4: Assess the shape and spread of your data distribution.
- Compare data from different groups.
How do you describe descriptive statistics?
Descriptive statistics are brief informational coefficients that summarize a given data set, which can be either a representation of the entire population or a sample of a population. Descriptive statistics are broken down into measures of central tendency and measures of variability (spread).
What method is used to compute average or central value of collected data?
The mean is the arithmetic average, and it is probably the measure of central tendency that you are most familiar. Calculating the mean is very simple. You just add up all of the values and divide by the number of observations in your dataset. The calculation of the mean incorporates all values in the data.
Which measure of central tendency is obtained by calculating the sum of values?
The arithmetic mean
The arithmetic mean of a dataset (which is different from the geometric mean) is the sum of all values divided by the total number of values. It’s the most commonly used measure of central tendency because all values are used in the calculation.
What are the 3 summarizing techniques?
There are three important summarization techniques. They are selection, rejection and substitution.
What are the 5 strategies in summarizing?
The Five W’s, One H strategy relies on six crucial questions: who, what, when, where, why, and how. These questions make it easy to identify the main character, important details, and main idea.
What does range of data mean?
In statistics, the range is the spread of your data from the lowest to the highest value in the distribution. It is a commonly used measure of variability. Along with measures of central tendency, measures of variability give you descriptive statistics for summarizing your data set.
Which method can be used to find the range of a set of data?
The range is the simplest measurement of the difference between values in a data set. To find the range, simply subtract the lowest value from the greatest value, ignoring the others.
What is the term used to describe the distribution of a dataset with one mode?
A distribution with a single mode is said to be unimodal. A distribution with more than one mode is said to be bimodal, trimodal, etc., or in general, multimodal.
How would you describe the center and spread of data?
The center is the median and/or mean of the data. The spread is the range of the data. And, the shape describes the type of graph. The four ways to describe shape are whether it is symmetric, how many peaks it has, if it is skewed to the left or right, and whether it is uniform.
What are the three modes of summarizing data?
The three common ways of looking at the center are average (also called mean), mode and median. All three summarize a distribution of the data by describing the typical value of a variable (average), the most frequently repeated number (mode), or the number in the middle of all the other numbers in a data set (median).
What are the two main ways of summarizing data?
There are two main ways to explore the shape (distribution) of a sample of data values: Graphically – using frequency histograms or tally plots draws a picture of the sample shape. Shape statistics – such as skewness and kurtosis.
What are the four types of descriptive statistics?
There are four major types of descriptive statistics:
- Measures of Frequency: * Count, Percent, Frequency.
- Measures of Central Tendency. * Mean, Median, and Mode.
- Measures of Dispersion or Variation. * Range, Variance, Standard Deviation.
- Measures of Position. * Percentile Ranks, Quartile Ranks.
What is a descriptive type of data called?
Descriptive statistics are used to describe the basic features of the data in a study. They provide simple summaries about the sample and the measures. Together with simple graphics analysis, they form the basis of virtually every quantitative analysis of data.
Which of the following helps in measuring the central tendency of the dataset?
Mean, Mode, Median are the measures of central tendency. Thus the correct option is C.
What is the value that occurs most frequently in a set of data?
The mode
The mode or modal value of a data set is the most frequently occurring value. It’s a measure of central tendency that tells you the most popular choice or most common characteristic of your sample.
What do you call the value that occurs most frequently in a set of data?
The mode or modal value of a data set is the most frequently occurring value. It’s a measure of central tendency that tells you the most popular choice or most common characteristic of your sample.
