thulasi_k15 Started The Discussion:

Hii
I am doing my final year project in WORKPLACE STRESS. i have collected the data, i used chi-square, Anova for data analysis.now i want to use t-test & z-test for data analysis.How to use it? I have used 5 rating scale in my questionnaire i.e Agree, Disagree, Neutral, Strongly Agree, Strongly Disagree.Which one i have to use in order to support my hypothesis.

Example1: For T-test

out of 100 samples, 10 of them are dept. heads

Null hypothesis: All dept.head are feeling stress due to job responsibility.
Alt. hypothesis: Not all dept.head are feeling stress due to job responsibility.
Collected data
Experiencing stress due to job responsibility.
Agree-7, Disagree-1, Neutral-0, Strongly Agree-2, Strongly Disagree-0


Example2: For Z-test
Null hypothesis: 15% of the employees are feeling stress when working in shifts.
Alt. hypothesis: <15% of the employees are feeling stress when working in shifts.
Experiencing stress when work in shift.
Agree-6, Disagree-26, Neutral-38, Strongly Agree-10, Strongly Disagree-28

How to solve this??

Please see The T-Test where you find some info.
The discussions at One Sample T-Test with Likert Scale Questionnaire - Statistics Help @ Talk Stats Forum will highlight the deficiencies with your approach to using t-test to Dept. Heads problem.

Likert scale@Everything2.com this site warn against the use of t-test when Likert Scale is used.

All found at Likert scale + t-test - Google Search

I am sure you were capable of finding this info from the web before posting the query.

Have a nice day.

Can you tabulate all the results on an Excel spread sheet and send it to me? Use 5= Strongly agree and 1= Strongly Disagree sort of codes when entering data for each of the respondents for each of the questions. Questions at the top of the colums and the respondents in each of the rows.

If the data is confidentials, please drop me a private message and I will give my email ID.

Have a nice day.

Dear Kani, Please search the web for the info. Also, Kindly give more information about what you are doing and why you aree seeking the information. Have a nice day. Simhan

what i done is similar to percentage analysis. I didn't use excel sheet, i have done everything manually.For each statements in my questionnaire i got the results similar to this.
Agree-6, Disagree-26, Neutral-38, Strongly Agree-10, Strongly Disagree-28

i used this data for analysis of hypothesis with anova and chi square,
for ex: relationship exist b/w no. of family members & employees experience stress when their expenses are more than income.
for the statement "I experience stress when my expenses are more than my income" i got this result.
Agree-38, Disagree-6, Neutral-26, Strongly Agree-28, Strongly Disagree-2

i categorize the data according to the no. of family members, like this.

family mem. |Strongly Agree |Agree | Neutral | Disagree |Strongly Disagree
</=3 ............. 2................... 9.......... 2.......... 1................ 1
4 ..................11................. 22...........8 ......... 3................ 0
>4.................15.................. 7.......... 16......... 2................ 1

is it correct?

How to apply this sort of codes to my statements.
strongly disagree 1
disagree 2
not sure 3
agree 4
strongly agree 5

Yes, using such codings please tabulate the data. And also read the material at the weblinks provided for analysing data collected using Likert Scales.

thank u sir for ur rply

i've done my project in India Cements Ltd. now i'm in the position of preparing the report

i thought of doing the sign test for the facilities provided by ICL to the employees

so i've collected the data with the scale of yes, no and no option

but i've some difficulties to analyse

for doing sign test we have to eliminate the no option

and cosider only the yes and no for calculating n value

then how to find out the z value

can u explain the way of doing sign test...... pls........
