True or False
1. PIE CHART, HISTOGRAM, and BAR CHART can be produced when one select T-TEST statistical function.
2. Descriptive statistics are run when researchers want to find out relationship between phenomena, such as if a higher gas price leads to more use of public transportation system.
3. In SPSS, DATA VIEW allows researchers to see actual numerical data that researchers have entered.
4. When running SPSS to generate PEARSON CORRELATION, one will use ANALYZE-à CORRELATE.
5. In PEARSON CORRELATION, r=1 means perfect positive correlation.
6. Univariate analysis procedure is the analysis of two variables.
1. False
when we select T-TEST satistical function we get results of t test and not pie chart ,histigram and bar chart. to produce this graphs we have to select Graphs menu and chart builder option.
2. True
descriptive statistics can help to summarize the relationships between variables using tools such as scatter plot. descriptive statistics is divided into two parts one is sorting/ grouping /and visualization of data and another is summary statistics of data.so in visualization of data we can find the relationship between variables.
3. True
in SPSS, in data view section we can see our actual data while in variable view we see additional information about our data.
4. True
in SPSS, to generate pearson correlation we go through Analyze> Correlate> Bivariate.
5. True.
when r=1 ,pearson correlation interpreted as the there is perfect positive correlation in two variables. positive since r has +1 value.
6. False
Univariate analysis procedure is analysis of one variable while analysis of two variables is Bivariate analysis procedure.
