#### Respond to at least one colleaguesâ€™ post with a comment on the presentation and interpretation of their analysis. In your response, address the following question

- Was the presentation of results clear? If so, provide some specific comments on why. If not, provide constructive suggestions.
- Are you able to understand how the results might relate back to positive social change? Do you think there are other aspects of positive social change related to the results?

**Continuous Variable:**

In the General Social Survey dataset found, â€œRespondents Incomeâ€ variable was selected as the

continuous variable for the descriptive statistics

**Mean** = 34554.85, **Median** = 24017.50 and **Mode** = 33255

**What might be the better measure for central tendency? (i.e., mean, median, or mode) and why?**

Regarding the better measure for the central tendency, Mean appeared to be the most frequently used measure of central tendency and generally considered the best measure of it. However, there are some situations where either median or mode is preferred. Median could be the preferred measure of central tendency when there are a few extreme scores in the distribution of the data, or when there is an open ended distribution e.g. if one have a data field which measures number of children and the options available are 0, 1, 2, 3, 4, 5 or â€œ6 or more,â€ then the â€œ6 or more fieldâ€ is open ended and makes calculating the mean impossible, since we do not know exact values for this field. And mode could be a preferred measure as well when data to be measured are in a nominal, even sometimes ordinal scale.

**Report the standard deviation = 33386.514**

**How variable are the data? **How variable data are referred to how dispersed a set of data is (Frankfort-Nachmias & Leon-Guerrero, 2018). And it can be described in terms of range, variance, and standard deviation. In this case the range = 158287, variance = 1114659343 and the standard deviation = 33386.514.

**How would you describe this data?** This data shows the changes in the income categories across years, and the changes in the nominal income distribution wrought by inflation have caused changes in the income variable (Ligon, 1988).

**What sort of research question would this variable help answer that might inform social change**?

What is the relationship between the disposable income of the respondents and location amongst young adults?

**Categorical Variable**

The categorical variable selected is Marital Status; a nominal variable.

**A frequency distribution.**

Married = 1158

Widowed = 209

Divorced = 411

Separated = 81

Never Married = 675

**An appropriate measure of variation – This i**s the **range** which is the difference between the largest and smallest values in a set of values; 1158 – 81 = 1077

**How variable are the data**? How variable data are referred to how dispersed a set of data is (Frankfort-Nachmias & Leon-Guerrero, 2018). And it can be described in terms of range, variance, and standard deviation. In this case Range = 4, Variance = 2.823, and Standard Deviation = 1.680

**How would you describe this data?**

This data shows the differences and changes in the marital status of a group of people and the changes in the nominal status distribution that could result in significant changes to oneâ€™s financial situation.

**What sort of research question would this variable help answer that might inform social change?**

This variable can help answer a question such as; Can economic benefits of marriage mediate the association between marriage and health?
