Harvard Business School SPSS Hypothesis Testing Project

Assignment 5: T-test, one-way ANOVA, two-way ANOVA and hypotheses testing INTG1-GC 1055Complete the following exercises. Make sure to include ALL calculations and outputs to receive
full credit. Be concise and specific in your answers. Please provide all tables and interpretations
of results where needed in Word or PDF file. Provide Output file as PDF.
1) SPSS hypothesis testing
Open CovidEmployeesFIN1055.sav in SPSS and check all variables and examine data
Please test following hypotheses and use 7-step approach for each hypothesis. Each hypothesis
is caring the same number of points:
a) H1: Average monthly earnings before Covid19 crisis (EarningsPreCovid) of service
industry workers were above $3000 – Compare mean to predetermined value and check
direction
b) H2: Average monthly earnings before Covid19 crisis (EarningsPreCovid) of service
industry workers were higher than average monthly earnings after Covid19 crisis
(EarningsPostCovid) – Compare means and check direction
c) H3: Service industry workers that are paid annual salary had a bigger reduction in
earnings (EarningsPostCovidPercent) than those that were on hourly wage – Compare
means and check direction
d) H4 – More service industry workers are paid wage than salary (EarningsType) – Compare
frequencies to expected values and check direction
e) H5 – Service industry workers that are paid annual salary are less likely to be on unpaid
leave (EmploymentStatus) than those that are on hourly wage – Compare frequencies in
crosstabulation table and look at subscript to determine specific differences in
frequencies/proportions between groups
2) SPSS ANOVA with Post-hoc analysis
Open Hotel Room Design.sav in SPSS and check all variables and examine data.
Please test hypothesis and use 7-step approach.
3) SPSS Two-way ANOVA/ANCOVA
Open Hotel Room Design.sav in SPSS and check all variables and examine data
Please formulate hypotheses based on research question and then test hypotheses using 7-step
approach for each hypothesis.
