What are the merits and demerits of central tendency?
The measures of central tendency are mean, median, and mode. The merits of mean are that it is easily calculated and easy to understands. Demerits are that it may be theoretical and cannot be used for qualitative date.
What is measures of central tendency as it relates to quantitative descriptive statistics?
They are the mean, median and mode.
Which descriptive statistics are appropriate for qualitative variables and what are appropriate for quantitative variables and why?
For qualitative variables, appropriate descriptive statistics include frequencies and proportions, as they help summarize categorical data and show the distribution of different categories. For quantitative variables, measures such as mean, median, mode, range, variance, and standard deviation are suitable because they provide insights into the central tendency, spread, and overall distribution of numerical data. The choice of statistics depends on the nature of the data: qualitative data is categorical and non-numeric, while quantitative data is numeric and can be measured.
When is mode the best of measure of central tendency?
never * * * * * When the data are qualitative. The mean and median are unusable in such cases and the mode is the only sensible measure.
What are the advantages and disadvantages of measures of central tendency?
One advantage to using central tendency is the fact that is represents all data. A disadvantage to using central tendency is the fact that extremes can skew the data.
What are the merits and demerits of central tendency?
The measures of central tendency are mean, median, and mode. The merits of mean are that it is easily calculated and easy to understands. Demerits are that it may be theoretical and cannot be used for qualitative date.
When is each measure of central tendency most useful?
Mode: Data are qualitative or categoric. Median: Quantitative data with outliers - particularly if the distribution is skew. Mean: Quantitative data without outliers, or else approx symmetrical.
Which measure summarizes all of the values of a data set with a single number?

What measure of central tendency would be most useful in describing the gender of a sample?
Since gender is a qualitative variable, the mode is the only one of the main measures of central tendency.

What is the central difference between qualitative and quantitative?
Qualitative and Quantitative determiners are used before nouns. Qualitative determiner is a describing word or adjective used before noun to show the quality of the noun. Eg.: Beautiful picture Beautiful - qualitative determiner or qualitative adjective Quantitative determiner is used before uncountable nouns to show the quantity of the noun. Eg.: A kilo of rice A glass of water A kilo of, A glass of - quantitative determiners rice, water - non count or uncountable nouns Note: Determiners are also known as Adjectives. Before the countable nouns we use Numerical Determiners. Eg.: Three apples Three - Numerical Determiner apples - Noun Hope I could help you out. All the Best!
When is finding the average not useful?
There is no meaningful average wen data are categorical (qualitative). Also, the arithmetic mean is not a good measure of central tendency when the data distribution is skewed.
