Answer to Problem 1TY

Correct answer:

Polygons and histograms are examples of the frequency distribution. This information is reflected in the option “a”. Therefore, option a. is correct.

Option a. is given as “frequency distributions”.

Explanation of Solution

Reason for the correct statement:

The frequency distribution is a tabular or graphical representation of different numbers or set of data. Histogram and polygons are the examples of the frequency distribution. The histogram is a bar graph which depicts the frequency distribution of a particular data. Polygon is a linear graph representation of frequency distribution.

Hence, option a. is correct.

Reasons for the incorrect statements:

Option b. is given as “correlations”.

Correlation is that statistic technique which determines the extent of similarity between two variables. Histogram and polygons are not the examples of the frequency distribution. Hence, it is a wrong answer.

Option c. is given as “inferential statistics”.

Histogram and polygons are not the examples of inferential statistics. Inferential statistics is the analysis of a large set of numerical data to reduce the chance of error in measurement. Hence, it is a wrong answer.

Option d. is given as “mode”.

The mode is that value whose frequency is highest or whose value occurs maximum time. Histogram and polygons are not the examples of mode. Hence, it is a wrong answer.

Hence, options b., c., and d. are incorrect.

Conclusion

Histogram and polygons represent frequency distribution of a particular data or sample in the form of graphical representation.
