反之,我们reject the null hypothesis 证明实验结果是有统计学意义的。 12. 第十二章节 Significance testing (Chi-square) 显著性检验:卡方检验Chi-square X2 test 卡方检验用来用来检测两个变量之间是否有区别, 通常用表格的形式来展现,比如投掷硬币,有正反两面,我们投掷100次,看正面次数有多少,反面次数有多少,然...
Describing the distribution of discrete random variables with probabilities, tables, graphs, etc., including calculation of expected value and standard deviation Describing the distribution of a continuous random variable with a probability density function, a density curve, etc. including the concept of ...
State the 3 key ways a distribution can be described. Activities Lesson 1 Class Start Up Distribute & discuss syllabi. Warm Up: Purpose: Can complex objects and phenomenon be described with a few numbers? Design: Have each person describe themselves with 2 words and 2 numbers and see if ...
That way, when they get very, very, very close, the secant slope becomes tangent slope, and the line PQ becomes tangent line, or simply tangent. The Definition of Limit Intuitively: Use limits to describe the TENDENCY of a function as a variable approaches a given point, but NOT exactl...
Takes numerical values that describe the outcomes of some chance process. Standard deviation of a random variable The square root of the variance of a random variable σ X^2 . The standard deviation measures the variability of the distribution about the mean. Variance of a random variable σx^...
2) Look for the overall pattern (shape, center, spread) and for striking departures such as outliers3) Calculate numerical summaries to briefly describe center and spread4) ___ large number of observations lead to a smooth curve A density curve is a curve that - ___- ___...
We can highlight the penalized prior distributions4 for the spatial effect hyperparameters, which allow us to describe the distribution as the probability ( p ρ , p σ ) on lower/upper side of ( ρ 0 , σ 0 ) . Therefore, to perform the fit there are several configuration item which...

Describe how that dot plot would different from the dot plot we generated today. 2. The principal of your school wants to know if the backpacks are too heavy for the students in your class. Does our data collection process answer this question? If so, explain how. If not, how could ...
