If you are considering a single ordinal variable, determining the mode or median would be meaningful, but the mean or SD would not. Many researchers do consider likert-scale data to possess only ordinal qualities. However, leading research studies, for example in the marketing area, obtain measures such as means and standard deviations from likert-scale data. Indeed leading textbooks also follow this approach. One concern has been that the 'distances' between points on a likert scale are not equal, for example the 'distance' or 'difference' between a strongly disagree and disagree is not the same as the difference between disagree and neutral. A recent study discusses these issues, as well as demonstrating that data obtained from 5-point, 7-point and 10-point likert scales are approximately comparable in terms of mean score (once re-scaled) and various measures of variation and data shape.

Disadvantages of using Likert questionnaires include limited response options, potential for response bias, difficulty in interpreting ambiguous or neutral responses, and the inability to capture detailed nuances of opinions or attitudes.
The disadvantage of using this type of scale is that you can not make statements about some percentage of the population "agreeing" or "disagreeing" with something. The population is not being described in an absolute sense. You can only compare answers across groups or across similar samples over time. Additionally the rankings are dependent on the particular list given. For example, you might say that ice cream is good on a three point scale but very good on a 5 point scale.
Many researchers believe you should only report the results for individual likert items using the proportion of responses for each scale point. For example, 17% strongly agreed, 32% agreed, 10% neither agreed or disagreed and so on. The reason they say this is that likert data is not "equal interval" - the difference between strongly agree and agree is not the same as the difference between neutral and agree, for example. The data is said to be ordinal, not metric. However, this is actually not so much of an issue. Several research studies show have calculated the numerical difference between Likert-type scale points and showed they are very, very close to "equal interval". References for this are given in this paper: Dawes, John. "Do Data Characteristics Change According to the Number of Scale Points Used - an Experiment using 5-point, 7-point and 10-point scales", International Journal of Market Research Vol 50, no 1, 2008.

We were all ready to analyze the situation.
Can you analyze the geographic coordinates?
I will analyze the data to identify any patterns or trends.
To analyze oil droplet size using a stage micrometer, first calibrate the microscope by measuring the stage micrometer's known scale. Then, focus on the oil droplets and use the calibrated scale to measure their diameters by comparing it with the micrometer scale. Record these measurements for analysis and statistical processing to determine the average size of the oil droplets.
