Do revise all the p5s as well as examiner reports ... plus the standard deviation, standard error , t-test and chi-squared test

Hey can anyone tell me the difference between t-test and chi-squared test?

 

[beacon_of_light]

T-test is used when data has continuous variation/distribution ... you should know a continuous variation curve... or a bell-shaped curve...
Chi-squared test is used when data has discontinuous variation...

Bell shaped as in normal distribution curve? And one more thing, both of them have the same function rite? Cmiiw

yes bell shaped = normal distribution ...
yeah both have the same purpose to " see whether the results have a significant difference or are by chance"
