Option B
XXXXXXXX of XXXXXXXX (ANOVA)XX used XX compare two means of XXX XXXXXXXXXXX groups. XXXXXXXX of XXXXXXXX is XXXX to study the difference XXXXXXX two or XXXX than XXX groups at the XXXX time. It XX XXXX appropriate as it is considered XX be a XXXXXX XXXX as it may tolerate violations to it's assumptions (of normality) XXX XXXXX XXXXX reliable XXXXXXX.
XXXXXXXXXXX XX XXXXX:
Assumption XX normality: XX XXXXXX that the XXXXXXXXXX XX be studied XX normally distributed. XX the XXXXXXXXXX XX XXXXXX, results XXX XXXX accurate XXXXXXXXXXX statements.Assumption XX homogeneity of XXXXXXXX: The variances XX several populations are XXX same.Assumption XX XXXXXXXXXXXX: Selection XX elements XXXXXXXXXX XXX sample is XXXXXXXXXXX of XXXXXXXXX of any XXXXX XXXXXX.XXXXXXX are XXXXX XX XXXXXX XXXX XXXXXXXXXXX.
Thet-testis a XXXX of a XXXXXXXXXXX measure used to find out whether the difference XXXXXXX XXXXX XX XXX XXXXXX XX significant or not. XX XX XXXX when XXX variance of two populations is XXXXXXX. However, it XX assumed XXXX XXX dependent XXXXXXXX to XX studied fits XXXX XXX XXXXXX XXXXXXXXXXXX.
Explanation:
XXX do we XXX an XXXXX instead of XXXXXXXX t-tests?
XXXX the XXXXXXXXXX XX XXXXX of XXXX two groups XXX XX be XXXXXXX, XX XXX a t-XXXX. When XXX analysis XXXXXXXX means of more than XXX groups, XX XXXXXX XXXXX. This is mainly XXXXXXX a t-test involves large XXXXXXXXXXXX XXX with XXXX t-XXXX, there is a X% XXXXXX XX XXXXXX a XXXX I error. XX XX XXX t-test XXXXX XX XXX XXXX XXX XX XXXX, we increase XXX XXXXXX of XXXXXX a Type 1 XXXXX to XX%. XXXXXXX, XXXXX is a XXXXXX test XXX has the XXXXXXX to XXXXXXX XXXX errors.
For XXXXXXX: To XXXXX the means of three XXXXXX, say 'X', 'B' XXX 'C', if XX XXX ANOVA, it will involve a single computation. XXX obtained XXXXX XXXX XX clear and XXXXXX. XXX if XX XXX a t-XXXX, it will XXXXXXX XXXXXXX XXXXXXXXXXXX (9 computations). XXXXXXX, we will XXX a t-test XXXXXXX group 'X' and 'X'. Then, between 'A' and 'X', XXX then XXXXXXX 'X' XXX 'X' and so XX. This involves a complex XXXXXXX XXXXX includes several XXXXX XXXXXXXXXXXX. It XXXXXXXXXXXX XXXXXXXXX the XXXX XX XXXXXXXXX and errors.
