For which type of distribution of scores is the mean the preferred measure of central tendency?

– When scores are measured on an ordinal scale the median is always appropriate and is usually the preferred measure of central tendency.

Which is the preferred measure of central tendency for data on ordinal scale?

The median is usually preferred to other measures of central tendency when your data set is skewed (i.e. forms a skewed distribution) or you are dealing with ordinal data. However the mode can also be appropriate in these situations but is not as commonly used as the median.

Which is the only measure of central tendency that can be used for all nominal ordinal interval and ratio scales of measurement quizlet?

The mode is the only measure of central tendency that can be used with data from a nominal scale of measurement. The mode is also the only measure of central tendency that corresponds to an actual score in the data as it is the most frequently occurring score.

Which measures of central tendency can we use with each scale of measurement?

The 3 most common measures of central tendency are the mode median and mean. Mode: the most frequent value. Median: the middle number in an ordered data set.
…
When should you use the mean median or mode?

Which measure of central tendency is best for categorical nominal or ordinal data?

The mode is most useful when used with categorical (nominal or ordinal) variables and when there is a relatively small sample size.

Which measure of central tendency is best?

The mean is the most frequently used measure of central tendency because it uses all values in the data set to give you an average. For data from skewed distributions the median is better than the mean because it isn’t influenced by extremely large values.

Which measure of central tendency takes into account the magnitude of scores?

Which measure of central tendency takes into account the magnitude of scores? Explaination / Solution: The median can be easily computed by sorting the data from smallest to largest and counting the middle value.

Which measure of central tendency is most often used when the data has extreme scores?

Median. The median is the middle value in a distribution. It is the point at which half of the scores are above and half of the scores are below. It is not affected by outliers so the median is preferred as a measure of central tendency when a distribution has extreme scores.

Which measure of central tendency is most often used when the data has extreme scores quizlet?

Mostly commonly used measure of central tendency in normal distributions. A limitation or disadvantage of the mean is that it is sensitive to extreme scores ( outliers) in skewed distributions.

What is the best measure of central tendency for a unimodal and symmetric distribution that is on the interval or ratio level?

In a perfectly symmetrical unimodal distribution mean median and mode are identical. The mode is at the peak of the curve mean is closest to the tail and median is positioned between the mode and the mean. The median is the best measure of central tendency for skewed distributions.

Which measure of central tendency would be most appropriate in determining housing values?

Why would the median rather than the mean be the appropriate measure of central tendency in determining housing values in a particular community? a. The median is useful for measuring how much values deviate from one another.

Which measure of variation is preferred when the median is used as a measure of center?

The interquartile range is preferred when the median is used as a measure of center.

What do you mean by central tendency in statistics?

Central tendency is defined as “the statistical measure that identifies a single value as representative of an entire distribution.”[2] It aims to provide an accurate description of the entire data. It is the single value that is most typical/representative of the collected data.

What are the characteristics of good measure of central tendency?

Explanation:

• it should be Well defined and rigid.
• it should be easy to understand and calculate.
• it should be based on all the observations of the data.
• it should be suitable for further algebraic operations.
• it should be a stable measure.

What is the most reliable measure of variability?

The standard deviation is the most commonly used and the most important measure of variability. Standard deviation uses the mean of the distribution as a reference point and measures variability by considering the distance between each score and the mean.

Which measure of central location is meaningful when the data are categorical?

Typically you use the mode with categorical ordinal and discrete data. In fact the mode is the only measure of central tendency that you can use with categorical data—such as the most preferred flavor of ice cream.

Which central tendency is more accurate Why?

The mean is the most accurate way of deriving the central tendencies of a group of values not only because it gives a more precise value as an answer but also because it takes into account every value in the list.

Which is the best suitable measure of central tendency to construct index number?

In statistics the three most common measures of central tendency are the mean median and mode. But geometric mean is use in construction of index numbers. Hence option (2) is correct.

What measure of central tendency best describes the center of the distribution?

Since the data set is not​ skewed the central tendency that best describes the​ “center” of the distribution is the mean. The arithmetic mean of a variable is computed by adding all the values of the variable in the data set and dividing by the number of observations.

What is often the preferred measure of central tendency if the data are severely skewed?

The median is usually preferred to other measures of central tendency when your data set is skewed.

Which of the following measures of the central tendency suits the data best if the objective is to assess the distribution of values?

Mean and median don’t make sense in categorical distributions. So mode describes central tendency at best.

Which of the following is the measure of central tendency Mcq?

Mean median and mode are all measures of central tendencies. median.

Which measure of central tendency is most affected by extreme data Scores pieces also known as outliers )?

The mean of 9.09 is misleading as only one score is greater than 9.09. When there are a few extreme scores called outliers the median is preferred to the mean as a measure of central tendency because the median is less affected by these extreme scores.

Which measure of central tendency is best for describing qualitative data?

If the data being analyzed is qualitative then the only measure of central tendency that can be reported is the mode. However if the data is quantitative in nature (ordinal or interval/ratio) then the mode median or mean can be used to describe the data.

Which measure of central tendency is obtained using the middle score when all scores are organized in numerical order?

Median = “middle” data point (or average of two middle data points) when the data points are arranged in numerical order.

Which measure of central tendency is most affected by extreme high or low scores?

The median gives the greatest weight to elements in the middle of the ordered data. When there are extreme numbers in the data set (very low or very high numbers) the median is a good choice for a measure of central tendency.

Which measure of central tendency would be best to describe the following set of data quizlet?

The mean is the most reliable measure of central tendency. Multiplying every score in the sample by 2 would double the value of the mean. The mean is resistant to extreme observations.

What is the preferred measure of central tendency quizlet?

When scores are measured on an ordinal scale the median is always appropriate and is usually the preferred measure of central tendency.

What calculation is preferred for the central tendency and spread if the distribution of values is skewed?

The median is usually preferred to other measures of central tendency when your data set is skewed (i.e. forms a skewed distribution) or you are dealing with ordinal data.

Which of the following measures of central tendency is best for nominal data quizlet?

Which of these measures of central tendency works for nominal variables? – Both the mean and the median work for nominal variables.

Which of the following measures of central tendency will be the most appropriate to use if the data relate to rates proportions and ratios?

Mean is generally considered the best measure of central tendency and the most frequently used one. However there are some situations where the other measures of central tendency are preferred. There are few extreme scores in the distribution.

Which measure of central tendency that is suitable to represent the data explain your answer?

The median is the safest and best measure of central tendency because it is not as influenced by the vagaries of observed data.

Which measure of central tendency takes into account the magnitude of scores?

Which measure of central tendency takes into account the magnitude of scores? Explaination / Solution: The median can be easily computed by sorting the data from smallest to largest and counting the middle value.

Which measure of center best represents the data?

The mean and the median can be calculated to help you find the “center” of a data set. The mean is the best estimate for the actual data set but the median is the best measurement when a data set contains several outliers or extreme values.
