Likert scale data is ordinal data. You cannot perform arithmetic operations on ordinal data and thus cannot calculate a mean or standard deviation. However, you can sum together the data from multiple Likert scale questions and then treat that sum as interval data. You can calculate a mean and standard deviation for interval data.
Assign the answer options numerical values, e.g., strongly disagree = 1, disagree = 2, neutral = 3, agree = 4, and strongly agree = 5. Then Add all scores together and divide by number of scores/questions to obtain mean.
@@npateaching5804 Thank you sir can you tell me, in my dissertation have 3 objectives and 2 hypothesis which technique will i use to achieve those objectives
Individual Likert-type questions are generally considered ordinal data, because the items have clear rank order. Overall Likert scale scores are sometimes treated as interval data. That is the scales that are created by summing the items which are often treated as interval.
Hi Sir, can u help me with a data analysis?
My assignment due date is closeby
Extraordinary explanation 💓
And analysis is too good
Very well explained sir , Thank you
Very nicely explained ! 💝
Very great video
Good one
Keep going
This was helpful! How would you handle a missing data point? Average the other data points for that respondent and replace or omit? Other?
👍
great video..pls provide references of the concepts shared here
Sir , what is pilot study and pretest ?
Sir how to find the mean and sd of likert scale

Also called psychometric scale?
How to know whether it's ordinal or interval data

There are no examples but only theoretical explanation
