GDC steps Flashcards
grouped data (ex - 0-500)
enter the mid value in one list, and the frequency in another
simple data
choose 1VAR after entering data and relevant information
statistical diagrams
enter data into lists. GRAPH then SET. choose diagram type, and list placement.
calculating probabilities when given boundries
DIST - NORM - NCD - enter lower and upper boundries, std and mean. click CALC
calculating boundries when given probability
DIST - NORM - INVN, set data as variable, choose tail, area (0-1), std, mean, CALC
probability for a specific outcome
DIST - BINM - BPD, data as variable, x = number of successes, n = number of trials, p = probability of success, CALC
calculating cumulative fequency
DIST - DINM - BCD, data as variable, x = maximum number of successes
calculating boundries when given probability
DIST - BINM - BCD, data as variable, area = the probability in the range (0-1), numerical = number of trials, p = probability of success
correlation coefficient, r
enter data, choose CALC, SET, REG, X, AX+B
drawing scatterplot with regression line
enter data, GRPH, SET, graph type, exit, GRH1, CALC, X, AX+B
spearman’s rank, rs
rank data, and then use same method for correlation coefficient
chi squared - entering observed values
TEST, CHI, 2WAY, choose wanted matrix and then execute, enter dimensions and enter observed data
chi squared
enter observed data, set matrix for expected to be empty,
chi squared
enter observed data, set matrix for expected to be empty,then execute
chi goodness of fit
enter data into lists, observed into list1 and expected into list2, TEST, CHI, GOF, execute
