- 1What formula is this?Anova
- 2What formula is this?Chi-square
- 3What does the following stand for in the chi square formula: o e Σo = observed
e = expected
Σ = the sum of - 4What does the following stand for in the standard deviation formula: S Σ x̅ ns = sample standard deviation
Σ = the sum of
x = sample mean
n = number of cases in sample - 5What does the following stand for in the sample mean formula? n Σxn = number of cases in sample/size of sample
Σx = the sample of all data values - 6What does the following stand for in the Anova formula? MS between MS withinMS between = mean between groups
MS within = mean within groups - 7What formula is this?Standard Deviation
- 8What formula is this?Sample Mean
- 9What data can you run a frequency test on?All three:
Nominal, Ordinal and Scale - 10What data does a crosstabulation analyse?Nominal and ordinal data
- 11What data does a One Sample T-Test analyse?Scale or Interval data
- 12What data does a One Way Anova analyse?A nominal or ordinal variable with a scale variable.
- 13What data does a Bivariate Correlation analyse?Two pieces of scale data.
- 14What variable types do the following symbols represent?Three circles = nominal
Three bars = ordinal
Ruler = scale
- 15What variable could be defined as fitting into an underlying numeric continuum?Interval/Scale data
- 16What variable could be defined as having values representing categories with an intrinsic ranking?Ordinal
- 17What variable could be defined as having values representing categories with NO intrinsic ranking?Nominal
- 18How do you calculate the mean, median and mode quickly?Enter all variables into a blank column on the data view screen. One you have entered the values run a frequency test which selects all three of the statistics. You results will be in the statistics box.
- 19What calculation would you do to find 68% of 804? What is the answer?(68 ÷ 100) x 804
Answer is: 546.72 - 20What calculation would you do to find out what percentage 86 is of 92? What is the answer?(86 ÷ 92) x 100
Answer is 6.61%. - 21What must the value be below for a test to be significant?.05
- 22What main columns do you read for a frequency test?Frequency and valid percent.
- 23Where do the independent and dependent variables go in a crosstabulation?Independent goes in column
Dependent goes in row - 24What percentages do you select for a crosstabulation?Column
- 25What test uses a chi-square to test for significance?Crosstabulation
- 26If you were asked to compare gender (nominal) with number of books read in the last year (ordinal), what test would you use?Crosstabulation
- 27If you were asked to compare age (ordinal) with opinion of how effective the police are (scale), what test would you use?Anova
- 28If you were asked to compare age (scale) with average BMI (scale), what test would you use?Correlation
- 29If you were asked to find the relationship between two variables, what test would you use?Correlation
